Are you saying that sometimes it can write to the xml file and sometimes it cannot?
It sounds like a permissions issue.
When access fails, who "owns" the .xml file?
When access fails, are you able to open the .xml file in r/w mode?
Note: I'm also running v12.10 SR3 and not having any issues. But I'm only running a single server.
Thx jrepucci15 for ur reply. We found a solution / the reason for our problem.
We are running a backup saving our whole qv-environment. This causes the file-lock. We removed the backup for the specific folder and wohoo .. no problems anymore
