Thread stack size in Jira/Confluence Server

[Jose Luna]

Hi all, 

I have installed Jira and Confluence server, I know that I can set values for Java memory use but I don't know exactly what means Thread stack size but I know that I can left 0 value by default. Can you help me to understand what it is?

Hi Jose

welcome to the Atlassian community.

 Each thread in the VM get’s a private stack to store call stack information, local variables, and partial results.

The stack size will limit the number of threads that you can have. To modify the stack size you can change the -Xss setting for your JVM configuration  If the stack space is too small, eventually you will see an exception class java.lang.StackOverflowError.

Hope that helps

Cheers

Kurt
