@Srikanth Gogineni:

update JIRA to a supported version (i.e. 7.6 Enterprise) <- !
create gc-logfiles and investigate on them
raise your JVM heapspace to i.e. 16GB (same min / max)

What exactly are the memory errors you get, and is there a trigger? For example, it happens when you run an export or a particular board?

Don't just try throwing memory or resource at this, you can make it worse if you don't know why you're doing it and how it might improve.

Hi Nic/ Lennart,

we are getting the below memory errors, when the users performing some actions like searching,editing, moving the issues.

/secure/ClonePlusDetails.jspa [jira.issue.index.DefaultIndexManager] Wait attempt timed out - waited 30000 milliseconds
com.atlassian.jira.issue.index.IndexException: Wait attempt timed out - waited 30000 milliseconds

Uncaught exception thrown by REST service: GC overhead limit exceeded
java.lang.OutOfMemoryError: GC overhead limit exceeded

rest/issueNav/1/issueTable [NoModule] There was an error getting a DBCP datasource.
java.lang.RuntimeException: Unable to obtain a connection from the underlying connection pool

and the CPU usage is high(around 70 to 90%) most of the time and the application is getting down during 6 pm to 7 pm IST time .

we have McAfee Service installed in the Server but that service is not taking much allocation from CPU

Let me know if you need any other details .

exlude JIRA files and folders from scanning (again, to be in support): https://confluence.atlassian.com/jirakb/anti-virus-in-jira-applications-398393384.html
- your antivirus could be the cause for your problems - check this documentation too
a higher cpu usage of JAVA could also be related to gc running too frequently (@Nic Brough -Adaptavist- is totally right, a bigger HeapSpace doesn't always help and is sometimes even worse - still, your issues could also be related to HeapSpace sizing)
check this documentation on how to stabilize your db-connection
again, update your JIRA instance to JIRA 7.6 (this should give you some performance and bring you back into developer-support)

My guess: Your antivirus causes the main issues.

Hi Lennart/ Nic,

below is the JVM configuration, please suggest me to add/remove anything from this configuration.

-Dcatalina.base=C:\Program Files\Atlassian\JIRA
-Dcatalina.home=C:\Program Files\Atlassian\JIRA
-Djava.endorsed.dirs=C:\Program Files\Atlassian\JIRA\endorsed
-Djava.awt.headless=true
-Datlassian.standalone=JIRA
-Dmail.mime.decodeparameters=true
-Dorg.apache.jasper.runtime.BodyContentImpl.LIMIT_BUFFER=true
-Djava.io.tmpdir=C:\Program Files\Atlassian\JIRA\temp
-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager
-Djava.util.logging.config.file=C:\Program Files\Atlassian\JIRA\conf\logging.properties
-XX:MaxPermSize=1024m
-Dhibernate.show_sql=false
-Dfile.encoding=UTF8
-XX:+UseParallelGC
-Duser.language=en
-Duser.country=US

here is the DBconfig configuration

pool-min-size>80</pool-min-size>
<pool-max-size>80</pool-max-size>
<pool-max-wait>60000</pool-max-wait>
<validation-query>select 1</validation-query>
<pool-max-idle>80</pool-max-idle>
<pool-remove-abandoned>true</pool-remove-abandoned>
<pool-remove-abandoned-timeout>300</pool-remove-abandoned-timeout>
</jdbc-datasource>

we are facing severe crashes which impacting business very badly
