I have a linux guest under VM 4.2 (SLES 7 - Patch CD1 - k_timer 2.4.7-9) The last few days, we have seen on three occasions were the box is partially hung. I can ssh in fine, I can cat/vi files no problem, but any process related commands (ps, top, etc) hang without any response after pressing enter. Procinfo shows the box is 96-98% idle at the time but more importantly we see the context field in procinfo incrementing wildly (Peak rate of about 50,000,000 switches per minute!). Netstat will work, however if you include the -p switch to see what processes are associated with the network connections it will also hang. It doesn't ever seem to recover from this situation, and the only way we have found to get out of it is to logoff the guest from VM, which causes as big a mess as one would expect from having to hit the virtual recovery switch.
The only application on this box is a java based application which uses RMI connections between the clients and DB2/UDB. Any suggestions on how to help narrow down what process(s) specifically are going haywire would be appreciated. I had seen somewhere in the past there were ways to "peek" into a running linux guest from VM to see what was going on in there, if anyone can point me to some type of recipie on doing that I would appreciate it. Any other suggestions on where to look or what to do is also appreciated Thanks in advance Jeremy Warren
