Hi,

Can you describe more that when OR in which scenario you are getting this error? There is already one bug opened for this issue https://bugs.launchpad.net/percona-server/+bug/1025407 but its unresolved, might be it needs more information. Can you make a test case and add those information in it? Steps which you performed and full error log can be helpful.
