Correlation Engine hang

Correlation Engine hang

Hey everyone
Couple days ago I upgrade EventLog Analyzer from version 11041 to 11100.
Now I observe problem with Correlation Engine - when I start service everythink works good, but after about two hours logs do not correlate until restart ELA service and over and over. Others functions seem work fine.

Environment:
EventLog Analyzer 11.10 (11100)
Windows Server 2008 R2 SP1 x64
MSSQL 9.00.5292.00

                New to ADSelfService Plus?
