I have a DFM issue in LMS 3.1. I upgraded from LMS 3.0 2007 Update to LMS3.1, and after a while, DFM started to produce interesting things. It "stops" sending alerts and notifications, and unable to load the alerts and activities page. All the DFM related services seems to be running. I already made a DFM database reinit, installed DFM 3.1.1 Patch, and both of them repaired the issue, but after 1-2 days it rise again.
The only thing which seems to be strange to me, that the memory usage is 5.8GB, and in LMS 3.0 it was only about 4GB. At the first occasion of the problem there were "java.lang.OutOfMemoryError: Java heap space" messages in adapterserve.log, and AdapterServe and AdapterServe1 processes were stopped.
Any ideas what can cause the problem?
