Deadlock detected on startup error in logfile
Symptoms
JIRA fails to start up.
The following appears in the atlassian-jira.log:

This can happen during JIRA's startup, and not consistently.
Cause
The message is logged anytime a deadlock is detected during JIRA's startup.
There are different factors that might cause a deadlock when JIRA is starting up:
- There is a bug existing on the Java JDK 7 that is the root cause of some deadlocks, see http://bugs.java.com/view_bug.do?bug_id=8044572 for more details.
- One of the plugins that your JIRA instance has installed is badly written, and has a bug causing a deadlock.
Resolution
There are two options to avoid having this problem at the moment:
- Restart JIRA
- If you are using JIRA 6.3 or higher, upgrade your Java JDK to JDK8, since that version does not contain the bug that causes this issue. 6.3 is the first version of JIRA that supports Java 8 so DO NOT upgrade your JDK if you are using an older version of JIRA.
