GC overhead limit exceeded at startup after "Installing DBCP monitoring instruments"

Hi,

We migrate jira 6.x 32 bits (test 6.0.8 and 6.1.4 - Xmx1200m) from jira 4.3.3 and we have a problem "GC overhead limit exceeded" when we start, every time at the same moment :

You would require to include certain parameters in order to fix the issue, please see https://confluence.atlassian.com/display/JIRAKB/JIRA+Crashes+Due+to+OutOfMemoryError+GC+Overhead+Limit+Exceeded for more information.

The problem comes from the LDAP synchronisation. It's takes 50 mins and shedule every 60 mins.

The CPU and Memory goes up. So synchronisation is every 24h now.
