Rediscovery Notes: LMS processes can get stalled during the DRM reconfiguration due to LE shortage, and this can lead to DRM timeout and instance crashes. eg: 2011-08-25 10:03:45.232033 :Start affinity expansion for pkey 81885.0 2011-08-25 10:03:46.698163 : Expand failed: pkey 81885.0, 1885 shadows traversed, 853 replayed 1 retries The fix for this bug takes care of the problem by closing anti-locks first and also non-remastered locks to free up more LEs. Workaround Disable read-mostly locking by setting: _gc_read_mostly_locking=FALSE. Note: It is unlikely that interim patches will be produced for this issue. Hence please use the workaround above or move to 188.8.131.52 (or higher) where the issue is fixed.
