I'd love to look but task manager hangs when the problem occurs. It refuses to open and if already open, doesn't respond. -----Original Message----- From: Bob [mailto:bobmails@xxxxxxxxx] Sent: 26 September 2006 16:41 To: thin@xxxxxxxxxxxxx Subject: [THIN] Re: Servers gradually grind to a halt task manager... processes tab... set view to show handle count column. anything over 5k handles? over 50k?

Since rebuilding my farm from scratch to downgrade from PS4 to PS3 (don't ask - lots of pain there) - my W2K3 SP1, PS3 + hotfix rollup 05 servers regularly (but one or two at a time) grind to a halt. The first sign is that the list of users stops refreshing from a local or remote server, eventually going blank. Once this happens the server in question will open apps normally at the console but things like Task Manager do not run. The IMA service cannot be stopped or restarted and just ignores attempts to do either. Nothing is logged in any event log. The only way to restore normal service is to physically depower the machine. As you can imagine, I'm tearing my hair out over this and my users are having a spirited attempt to help. Can anyone suggest pointers or troubleshooting steps I can follow? ************************************************ For Archives, RSS, to Unsubscribe, Subscribe or set Digest or Vacation mode use the below link: //www.freelists.org/list/thin <//www.freelists.org/list/thin> ************************************************
