Symptoms

When the system fetches a dynamic user record from MySQL and places the record into memcache, the record might remain there in an unmodified state for ten days.

Impact

Dynamic user, if locked out, remains in memcache for ten days. During this interval, the dynamic user record is unusable.

Conditions

This occurs when a dynamic user record is removed from memcache but remains in MySQL, due to an intermittent race condition between apmd/memcache and localdbmgr.

Workaround

The Admin can remove the user by deleting the associated memcache record.

Fix Information

None
