Question

How to check if Jira Data Center is stuttering/restarting because it is maxing out its connection pools?

Answer

Look in the atlassian-jira.log file for errors like these:


2018-07-04 13:35:27,101 http-nio-8080-exec-19 url:/rest/api/latest/user WARN anonymous 815x659873x1 - 172.23.169.71:59200,127.0.0.1 /rest/api/latest/user [c.a.jira.ofbiz.ConnectionPoolHealthSqlInterceptor] Dangerous use of multiple connections: taken => count=2; marks=[1-0]; pool=315/50 2018-07-04 13:35:27,101 http-nio-8080-exec-19 url:/rest/api/latest/user WARN anonymous 815x659873x1 - 172.23.169.71:59200,127.0.0.1 /rest/api/latest/user [c.a.jira.ofbiz.ConnectionPoolHealthSqlInterceptor] Dangerous use of multiple connections: replaced => count=1; marks=[0-0]; pool=314/50 2018-07-04 13:35:27,116 http-nio-8080-exec-19 url:/rest/api/latest/user WARN anonymous 815x659873x1 - 172.23.169.71:59200,127.0.0.1 /rest/api/latest/user [c.a.jira.ofbiz.ConnectionPoolHealthSqlInterceptor] Dangerous use of multiple connections: taken => count=2; marks=[1-0]; pool=315/50

And for restarts or Broken connection/Broken pipe errors following this.

If found, client need to talk to Atlassian to understand the reason for this connection pools to be full.
