I have login API developed in spring boot and deployed on cloud run with min instance 1. But for some request it is taking 20s to process which is not desirable. When I checked logs, I found that application is starting again and it is taking time and most of request are processed within 100ms .Please suggest where Im going wrong.
I found that it was a cold start problem so kept min instance to 1. But still for some request it is taking more time than expected.
I am developing a Spring Boot Client cache application (spring-geode-starter version 1.7.5), which connects a gfsh locator and server ( say locator1 , server1).
During startup of the client application, spring boot automatically connects the locator and server running.
Now if I stop server from gfsh terminal , I observe in log, the client application gets notified with some log console messages.. also when i restart server from gfsh, i see client log message of auto reconnection done towards server.
My objective is : how to handle in some event listener in my client application code to get notified these disconnect and reconnect events, so that I need to do some extra logic work during these events.
can any one suggest and help me..
We are facing one problem, that sometimes our RabbitMQ server crashes due to some reasons. To connect RabbitMQ again with micro-services we need to restart the spring boot micro-services, Now is there a way that we can skip the restarts, so whenever RabbitMQ comes up, services' connection to RabbitMQ should automatically be created and should start working as expected.
We are having issue on rabbitmq that happens when we deploy the application on production, we are not able to reproduce the issue on our development environment.
We have a microservices architecture with multiple spring boot applications deployed on kubernates with autoscaler depends on the usage and we notice that after sometimes some Unacked messages are created in queue, the number of Unacked messages will increase with the time and after sometimes rabbitmq seems to stop working.
Is there something we can check in order to identify the problem?
I have created a spring boot integration app and deployed it to Pivotal Cloud Foundry (PCF) environment. It works for couple of days and then it starts to crash randomly afterwards. I checked the PCF logs and found this information about the crash.
OUTApp instance exited with guid 3c348d47-48c4-403f-950a-29af1efa551d
payload: {"instance"=>"e2122543-214f-4806-62c7-00e1", "index"=>2,
"reason"=>"CRASHED", "exit_description"=>"Instance became unhealthy: Failed
to make HTTP request to '/health' on port 8080: timed out after 1.00
seconds", "crash_count"=>1, "crash_timestamp"=>1511959503256098495,
"version"=>"10cea919-d490-460d-83d6-5132c96ef781"}
My CPU utilization is not much. My memory is also not leaking.
Information about the application deployed in PCF:
Spring boot integration app connects to IBM MQ queues and polls for messages and then calls couple of web services.
There is also another application Service Bus, which makes the health check call on PCF application to check if the PCF app is available or not. If Service Bus finds that PCF app is available then the requests are routed to PCF else they are processed at Service Bus end itself.
Please let me know, how to find the root cause of the CRASH and fix it.
Thanks in advance. Please let me know, if you need further details.
I have changed the health check type to port type from http in manifest.yml file.
configuration change in manifest file is as follows:
health-check-type: port
Now the app is not crashing. It is working fine. Hope this helps.
