If you watch the console long enough, do you see anything like: __alloc_pages: 0-order allocation failed
or VM: killing process? How large did you define the guest? How much is a "small amount" of swap? What kind of workload? What error message do you get when you try to log onto the linux console? Also, by default SLES8 kicks off sa every 10 minutes. If you're lucky you might get one of these "hangs" shortly after one of these 10 minute intervals. It might be interesting to check out the system activity data. Something like: /usr/bin/sar -u -r -f /var/log/sa/sa.2004_09_15 You can further narrow it if you want by specifying a start and end time, like: /usr/bin/sar -s 08:00:00 -e 09:00:00 -u -r -f /var/log/sa/sa.2004_09_15 ~ Daniel > -----Original Message----- > From: Linux on 390 Port [mailto:[EMAIL PROTECTED] On Behalf Of > Troyski > Sent: Wednesday, September 15, 2004 6:58 AM > To: [EMAIL PROTECTED] > Subject: Re: Guest freeze > > Just to let you know; I removed the samba client RPM from two of my > guests that exhibited the hang problem, but one at least one still > shows the problem.
