Re: [U2] CPU Spikes to 100%
I have 2 sites running on vmware virtualisation for Windows 2003 and a HyperV with Windows 2008 66 bit and have had no problems. I did have an issue of a .Net application with an old release of UniObjects .Net that caused the CPU to spike 100%. I recompiled the app with the new version and this problem went away. I do have a problem with the Telnet sessions freezing after a time of no activity on the VMware sites, but this has not caused a CPU issue.

From: Curt Stewart The environment is a virtualized Windows 2003 Server and Universe 10.2.10 On occasion, I've been notified twice, it may have occurred more often, a Universe process (tl_server.exe) will consume 100% of the CPU. Curt, I wasn't watching this tread earlier, sorry. This is the Exact same problem that Mike Roosa at Tolt is having, as documented in another recent thread here. Rocket has been unable to thoroughly diagnose the issue but tl_server does seem to be either the culprit or a telltale victim. I highly recommend you contact Rocket and tell them this may be related to the Tolt situation. Note that their environment is also virtualized in VMware. Perhaps there is something in VMware, like flushing, or some abnormal condition, which causes tl_server to start spinning. Good luck bud.

This sounds like a long-standing problem that I thought had been fixed some while back. We used to suffer this with UV9.6 on NT but I don't remember it with UV10/Win2K. We didn't have a virtualised environment at the time, so if it's the problem we had, it's nothing to do with VMware. Cheers, Wol -- Anthony W.

Re: [U2] CPU Spikes to 100%
Hi Curt, The keepalive setting affects the server where UV is running. The connections are tested for the existence of a client by sending keepalive packets. If the expected responses are not received within the parameters specified, they will be closed. This is standard to the protocol. Older versions of UV didn't allow for this, but I believe from 10.1 forward UV did.

Re: [U2] CPU Spikes to 100%
Curt, why not setup a phantom process, that just wakes up every five minutes or twenty minutes or whatever, and snapshots the activity? That would *at least* give you the opporunity of catching the beast in action without the need to be woken up at 2:30 in the morning to see it first-hand.

Re: [U2] CPU Spikes to 100%
Curt, We are also on a Windows 2003 virtualized environment and experiencing the exact same thing. We have been working with Rocket and our vendor a lot over the past couple of months trying to track this down, but have not done so yet. Just last week, Rocket suggested we add a second processor to that machine which we did and they also suggested unchecking the box interact with desktop in the Universe Telnet service. We did both of these last week and only had one problem this week which lasted about 2 minutes. Prior to making these changes we were seeing the issue about every other day so it looks like those suggestions may have helped, but still not completely fixed our problem.

Re: [U2] CPU Spikes to 100%
Yes, we have seen this happen quite frequently on our Windows 2003 virtual server. Go into Windows Services and find the Universe Telnet service and on the second tab (i think) there is a checkbox for interact with desktop. Make sure that's not checked. This is what Rocket told us. It hasn't completely fixed our issue but seems to have helped. Could be just luck though.
