JBPM 6.4: GC overhead limit exceeded

[Gul Md Ershad]

Hi Team,

My JBPM 6.4 was continuously running fine for one month but after that it started throwing below exception and then I shut down the server and then I tried running again but JBPM is getting up.

It encountered below error:

Did you perform a memory dump?

There was a leak that was fixed in 7.0, but only was a problem if there were lots of processes started per second .

Yes, we start lots of process per second. We dont' do any memory dump. is this required? If yes, then please guide me.
