Description Arvid Requate univentionstaff 2013-06-03 22:18:28 CEST
The behaviour of UVMM under load could be improved. Today I faced a couple of errors from UVMM, that appear to be caused by a high load (today mainly on the server "krus", but also on "isala").

Fehlernachricht des Servers:
Fehler beim Verwalten der Domäne "40178d0f-514b-0c86-0e33-a41fea9a9a88": Timed out during operation: cannot acquire state change lock
================================================================================

This may happen e.g. when a snapshot-revert takes very long, times out and another attempt is initiated by the user.

Benachrichtigung 
Ein unbekannter Fehler mit Status-Code 502 trat während des Verbindungsaufbaus zum Server auf. Bitte versuchen Sie es später noch einmal.

Probably this message communicates a timeout?
