Terveer) Newsgroups: comp.unix.sysv386 Subject: NOTICE: getcpages - waiting for 1 contiguous pages Keywords: Esix 5.3.2-D, panic Message-ID: <1991Jun14.202957.1408@hawkmoon.MN.ORG> Date: 14 Jun 91 20:29:57 GMT Organization: Home System (One of the Eternal Champions); Eagan, MN, 55123-2507, USA Lines: 75 My machine has been crashing at least once per day with the following panic which is preceded by a number of NOTICEs. I am not sure what the getcpages message indicates other than the obvious; that somewhere the kernel required at least one page of contiguous "memory". And because it was in swap (and swapchunk) when it died, i presume that the swapper paniced when it couldn't swap in? a page of memory from the swap device? I say "in" because I have 16MB of swap space allocated and i have never seen that dip below about 10MB available, even with X-windows running and lots of stuff going on. So, i find it hard to believe that Esix had trouble swapping out to the swap area on disk. That doesn't make much sense. But, i didn't have a lot of processes running; X-windows with some windows, vi, a compressed tape backup, news batching. I realize that 8MB of primary memory isn't a lot (and i intend to obtain more asap), but i kind of hoped that the system would simply get slower and page more of those 4k chunks in and out to accomplish its tasks instead of crashing. Am i deluded in this expectation? Also, on a related subject, if i am in x-windows these NOTICEs don't appear on any window that is visible from within X-windows and so i am unaware of the problems until after the panic and i have run crash after rebooting. Is there any way of getting an xterm to record the messages that go to the console? "Xterm -help" says that "xterm -C" is supposed to put the xterm into console mode, but "xterm -C" returns "bad command line option." I have tried various other possibilities like -c, -console, etc., with no luck. Sigh...
