I am using elasticsearch in a liferay portal (sidecar). Unfortunately, elasticsearch can only be startet as root user. Otherwise, I get a java native error in
org.elasticsearch.bootstrap.JNANatives.trySetMaxNumberOfThreads on bootstrapping:
V [libjvm.so+0x687142] InterpreterRuntime::resolve_invoke(JavaThread*, Bytecodes::Code)+0x1b2
j org.elasticsearch.bootstrap.JNANatives.trySetMaxNumberOfThreads()V+20
j org.elasticsearch.bootstrap.Natives.trySetMaxNumberOfThreads()V+17
j org.elasticsearch.bootstrap.Bootstrap.initializeNatives(Ljava/nio/file/Path;ZZZ)V+75
I have checked/updated the ulimits for the current user, but it seems like JNANatives is not allowed to execute this methods. The service starts fine as root, but I want to avoid any root processes on the server. Does someone had a similar problem? How can I debug this? What could be the issue here?
Many thanks
Now, I found the problem and want to share it here, so that anyone has a similar issues finds a possible hint.
I figured out that some folders up the hierarchy, there was a mount involved causing some permission issues. This causes a hotspot JVM native error in org.elasticsearch.bootstrap.JNANatives.trySetMaxNumberOfThreads().
Liferay reports java.io.StreamCorruptedException: invalid type code: 23 for elasticsearch.
I thought it was due to a ulimit, but it wasn't. Fixing mount/folder permissions on a top level folder, resolved the bootstrapping issues.

I am unable to create a new Common Data Service Database in my Power Apps default environment. Please see the error text below.
It looks like you don't have permission to use the Common Data Service
in this environment. Switch to a different environment, or create your
own.
Which as I understand I should be able to create after the Microsoft Business Application October 2018 update as listed in the article available at following link.
https://community.dynamics.com/365/b/dynamicscitizendeveloper/archive/2018/10/17/demystifying-dynamics-365-and-powerapps-environments-part-1
Also when I try to create a Common Data Service app in my default environment, I encounter following error.
The data did not load correctly. Please try again.
The environment 'Default-57e1485d-1197-4afd-b792-5c423ab508d9' is not
linked to a new CDS 2.0 instance. The operation 'ListInstanceMetadata'
is forbidden for unlinked environments
Moreover I am unable to see the default environment on https://admin.powerapps.com/environments, I can only see the Sandbox environment there.
Any ideas what I am missing here?
Thank you.
Someone else faced a similar issue and I read in one of the threads about deleting the browser cache and trying it again or trying it in a different browser resolved the issue. Could you try these first level steps and check if you still have these issues?
Ref: https://powerusers.microsoft.com/t5/Common-Data-Service-for-Apps/Default-Environment-Error-on-CDS/m-p/233582#M1281
Also, for your permission error ref: https://powerusers.microsoft.com/t5/Common-Data-Service-for-Apps/Common-Data-Service-Business-Flows/td-p/142053
I have not validated these findings. But as these answers are from MS and PowerApps team, hope it helps!
I just recently set up a FOIP server which involved configuring several different applications and one of them is freeswitch. I've searched and searched but haven't found a good solution for this problem, so I'll get right to it. This is the error message:
[ERR] mod_spanddsp_fax.c:1367 Cannot send non-existant fax file [usr/ictcore/data/document/document_1.tiff]
I have tired several things to troubleshoot the issue such as checking permissions, installing the correct dependencies, etc...so if that error message strikes anyone as something familiar please share. I can provide full logs per request.
Here's a hint for people who run into this stupid issue. Disable SElinux before changing any configuration files and make the changes permanent, otherwise a reboot will put you back right where you started.
I have a CodeIgniter setup that has been running fine for the past 2 months and recently I keep getting:
CodeIgniter error- unable to connect to database using the provided settings
I've recently added a new domain that has a landing page for the database login (zPanel), but I don't see how that could have caused a problem--maybe the page keeps getting directory attacked or something, but I'm not sure.
Is there a way to check if this is the problem through logs? I'm at dead ends with this problem, as when I restart the server (DigitalOcean) it works fine again.
Really not sure. If anyone else has had a similar problem, I'd love to hear your solution.
Thanks.
I think your mysql is going down so Codeigniter can't connect to your database settings.
Please login to SSH and check processes by "TOP" comment. See what is using resources ram or cpu.
And check your mysql conf settings, be sure that everything written if its empty it will cause alot of problems.
Some example :

For the past three to four months, we have our application live and running, we haven't deployed any new fixes / changes on Live. However ever unfortunately, we noticed that application has stopped running.
Following is the issue we observed from our logs :
"Can't create/write to file '/var/tmp/#sql_2f6_0.MYI" .
It would be really appreciable if anyone of you can extend your help.
Check the services and the User for which your Mysql is giving you this error. It is very much possible that any of the services might be down, or the User by which you are using the DB is not getting authenticated.
You or the user that handles your SQL service doesn't have permission to /var/tmp/. You can fix this by using chmod or Security permissions, depending on which platform you're on.
While running database configuration assistant(oracle 9i) I get error oversubscribed literal/length tree.Please help me out.
This is an instance of java.util.zip.ZipException. There are a number of things which might cause it. One cause is the executed path being too long, for instance if you extracted the zip to a sub-directory (instead of, say, the root).
But there are a number of other things which might cause it, e.g. file corruption. So if the directory path length is not the problem you will need to give us more details. For instance, what OS are you installing on? Also, is there any more info regarding the error in the log file: $ORACLE_HOME/assistants/opca/install.log?
