Hi All

I am currently using zcs-6.0.2_GA_1912.UBUNTU8_64 (Open Source Edition) and sometimes the zmmailbox process stops for several minutes. The entry in zmmailboxd.out is the following:

49663.762: [GC 49663.762: [ParNew (promotion failed): 93675K->90505K(94016K), 2.6561510 secs]49666.418: [CMS[Unloading class sun.reflect.GeneratedMethodAccessor217]

Total time for which application threads were stopped: 196.0071700 seconds


My GC configuration is the following:

$ zmlocalconfig mailboxd_java_options | fmt
mailboxd_java_options = -server -XX:NewRatio=2 -Djava.awt.headless=true
-XX:MaxPermSize=128m -XX:SoftRefLRUPolicyMSPerMB=1
-verbose:gc -XX:+PrintGCDetails -XX:+PrintGCTimeStamps
-XX:+PrintGCApplicationStoppedTime -XX:+UseConcMarkSweepGC

$ zmlocalconfig mailboxd_java_heap_new_size_percent
mailboxd_java_heap_new_size_percent = 25

Can anyone help?

Thanks
