After a period of dornmancy, the smart client auto-logoff will kick the user. This is not a gentle logout whereby all dialogues are closed and transaction rolled back smoothly. Locks and connections are left orphaned which eventually results in performance issues.
Error Message :- File: AtomicCache.cpp(1818) : Failed Assert: oAtomicCache::addToOrphanage -- Iref for non-meta-data object ( Class ID:6065, Object ID:1625000070, Ref Count:8 ) is being added to the meta-data orphanage. This is potentially a memory leak.
The auto-log of issue is being investigated in VSTS #14313. Until this is resolved, users are instructed to not use the auto-logoff feature.
Remove/do not use the -alt mm parameter from the Smartclient shortcut.
