I need a little help to understand what's wrong with by two rules.
RULE inefficient FilterOutputStream write trace

IF TRUE
DO traceStack("*** Slow write calls ***", 10)
ENDRULE
RULE inefficient FilterInputStream read trace

There is this in the console of the jvm
$ TransformListener() : handling connection on port 9091

Is there something else I should be checking ?

I use chromedriver headless
This is the command line that I use in jenkins
apache-jmeter-5.5/bin/jmeter.bat -n -t "test.jmx"
jmeter version 5.5
what is the problem and possible cause
also i get this message sometimes in the output
WARNING: Unable to find version of CDP to use for . You may need to include a dependency on a specific version of the CDP using something similar to `org.seleniumhq.selenium:selenium-devtools-v86:4.5.0` where the version ("v86") matches the version of the chromium-based browser you're using and the version number of the artifact is the same as Selenium's.
An unrecoverable stack overflow has occurred
it means that either you have an endless loop somewhere or create a large object which exceeds the thread stack size
The solutions are in:
inspect your code for any loop instances (for, foreach, while) which may fail to exit
increase stack size by passing the relevant -Xss argument
allocate another machine and switch to distributed testing mode with 750 users per machine
In general using Selenium for performance testing is not recommended, it might be a better idea to conduct the main load using JMeter's HTTP Request samplers and use 1-2 threads in another Thread Group running WebDriver Samplers to measure frontend performance, rendering speed, scripts execution time, collecting web vitals metrics and so on.
protoc-gen-validate is a protoc plugin to generate polyglot message validators.
The project uses Bazel for builds and has an open pull request to add support for customization of validation error messages.
The original code was made in 2020. Recently it was updated with the latest code, and after fixing all merge conflicts now it fails to build, but I can't find the issue:
~/GitHub/protoc-gen-validate (i18n) $ make bazel-tests

Judging by the fact that the error ([error] failed post-processing: 820:39: missing ',' in argument list (and 10 more errors)) appears immediately after I fire the tests command, I figure this is an issue with Bazel, but I'm not sure.
UPDATE 1: I narrowed it down to this:

make testcase works
Building with switch --sandbox_debug would provide an untruncated stacktrace.
It's all about one missing comma ...the only question is within which file and line.
It complains about the harness_py_proto tests # 46:21. Running a syntax check on file tests/harness/executor/cases.go suggested, because if 820:39 isn't in some generated file, this might be the file which fits best (by line numbers and also the error message). I'm not that fluent in Go syntax, that's why I cannot spot it at sight - but a syntax checker or linter could:
lint bazel testcases bazel-tests
Also the Makefile might be a possible candidate, but there's not much going on:
.PHONY: harness
harness: testcases tests/harness/go/harness.pb.go tests/harness/go/main/go-harness tests/harness/cc/cc-harness bin/harness ## runs the test harness, validating a series of test cases in all supported languages
./bin/harness -go -cc
.PHONY: bazel-tests
bazel-tests: ## runs all tests with Bazel
bazel test //tests/... --test_output=errors
Ever tried running make harness previously? When it does what the comment says ...
## runs the test harness, validating a series of test cases in all supported languages
I'm working on deploying application to WebSphere 7 using python script and the script is throwing exception at this line:-
AdminTask.listTCPEndPoints('abc(abc)')
If I run the above command before I run the python script, it works fine. It gives me an error ADMF0003E: Invalid parameter value. But the same command fails in the python script with this error:
wsadmin>AdminTask.listTCPEndPoints('abc(abc)')
WASX7015E: Exception running command: "AdminTask.listTCPEndPoints('abc(abc)')"; exception information: com.ibm.websphere.management.cmdframework.CommandValidationException: ADMF0007E: target object is required.
I can guess that there something in the python script that is causing this issue, but I don't understand why is the AdminTask.listTCPEndPoints command is not able to see the parameter being passed. I'm new to WebSphere, I have only used it in past but never configured it. Any help/insight would be highly appreciated.
Thanks!
Added stack trace of interactive mode option

Follow this link. It appears that you have not specified the target object that's why that error is coming.
I suggest use the following command as a starter
print AdminTask.listTCPEndPoints('-interactive')
Note: Instead of copying and pasting the command, type it on the command line. sometimes command editor does not take the command after pasting it directly.
Okay, I was able to fix the error. I was getting that error because as part of the application deployment script, I was copying few of my application jars to WebSphere's java/jre/lib/ext directory so that those are available in classpath. In one of those jar, I had bundled an IBM class (Base64Coder.class) which was required by a class in my jar and it was corrupting the WebSphere AdminTask utility. When I removed that Base64Coder.class from my jar, python script worked fine. I believe, the reason it corrupted WebSphere was that there was a duplication of the same class in the JVM as the class comes with IBM WebSphere installation and was present in AppServer/runtimes/com.ibm.ws.webservices.thinclient_7.0.0.jar
When i deployed jhipster web application to OpenShift, my app page getting "503 Service Temporarily Unavailable" and when I look at the log files, having the following problem;
==> app-root/logs/mapp.log <==
Unrecognized option: --spring.profiles.active=prod
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
Is there any solution you know?
That is not an option recognized by the JVM. In order to set system properties use use -D. From the Java 7 reference:
-Dproperty=value
Sets a system property value.
If value is a string that contains spaces, then you must enclose the
string in double quotation marks:
java -Dmydir="some string" SomeClass
In this instance you would use:
-Dspring.profiles.active=prod
It can then be acquired in your application by using the System class:
System.getProperty("spring.profiles.active")
I'm trying to build a simple cluster based on Windows XP. I compiled OpenMPI-1.4.2 successfully, and tools like mpicc and ompi_info work too, but I can't get my mpirun working properly. The only output I can see is

It looks like orte_init failed for some reason; your parallel process is
likely to abort. There are many reasons that a parallel process can
fail during orte_init; some of which are due to configuration or
environment problems. This failure appears to be an internal failure;
here's some additional information (which may only be relevant to an
Open MPI developer):

Where z:\hosts.txt appears as follows:

host1
Z: is a shared network drive available to both host0 and host1.
What my problem is and how do I fix it?
Upd:
Ok, this problem seems to be fixed. It seems to me that WideCap driver and/or software components causes this error to appear. A "clean" machine runs local task successfully. Anyway, I still cannot run a task within at least 2 machines, I'm getting following message:

I googled a little and did all the things as described here: http://www.open-mpi.org/community/lists/users/2010/03/12355.php but I'm still getting the same error. Can anyone help me?
Upd2:
Error code -2147217400 might be WMI error WBEM_E_INVALID_PARAMETER (0x80041008) which occures when one of the parameters passed to the WMI call is not correct. Does this mean that the problem is in OpenMPI source code itself? Or maybe it's because of wrong/outdated wincred.h and credui.lib I used while building OpenMPI from the source code?
