Running Jira using all system cpu resources

Samuel Hapák1

I have just installed Jira on Debian 64bit linux server and it constantly uses 100% of both of my cpu cores. Jira is freshly installed, nobody uses it at the moment, but it still uses 100% of both of my cpu cores. I have no clue, were is the problem. So I just cannot let the Jira run on the server, because it has also other responsibilities. Any clue, where is the problem?

I have found the solution in this article http://blog.wpkg.org/2012/07/01/java-leap-second-bug-30-june-1-july-2012-fix/

There is a great chance, this is caused by the "leap second kernel bug". Firstly, check for the following in the `dmesg`

[10703552.860274] Clock: inserting leap second 23:59:60 UTC

To fix it, firstly stop the ntp client. On debian-like systems

/etc/init.d/ntp stop

Store the current time

date -s now

And test the java. If everything is working correctly, try to restart ntp service

/etc/init.d/ntp start

And test it again.
