Jira Core Upgrade to 7.9.1 or 7.6.5 problem: Index lock file(s) found.

[Markus Braun]

Hi Community!

I've got a weird problem when updating Jira to the latest versions last week and through I'll ask if anyone is experiencing the same issue (or has some hint for me what to do).

When trying to upgrade from Jira Core 7.5.0 to Jira Core 7.9.1 with the linux installer (on a CentOS 6 VM Ware box) I get the following error (in log as well as on the error page):

*****************************************************************************************************************
Index lock file(s) found. This occurs either because JIRA was not cleanly shutdown
or because there is another instance of this JIRA installation currently running.
Please ensure that no other instance of this JIRA installation is running
and then remove the following lock file(s) and restart JIRA:
UtilConcurrentLock

{lock=true, fullLockName=/var/atlassian/application-data/jira/caches/indexes/issues/write.lock}
Once restarted you will need to reindex your data to ensure that indexes are up to date.

Do NOT delete the lock file(s) if there is another JIRA running with the same index directory
instead cleanly shutdown the other instance.
*****************************************************************************************************************

However the file stated isn't even there on disk and there is no other Jira instance running.
Any stop/start/restart/shutdown is resulting in the same problem.

So I resetted a VM snapshot and tried another version (7.6.5) with the exact same results.

Then I did a clean install (no upgrade) of Jira 7.6.5 with an xml backup import from old 7.5.0
That worked and Jira was available.

However this wasn't able to survive a restart. After rebooting the machine to test if the service autostart is working the error was present again.

Is there any known solution for this issue?

Best regards,

Markus
