Is there still a swap problem in Ultrix 4.0 or another problem that look like a swap eating problem? I'm running: ULTRIX V4.0 (Rev. 179) System#1: Tue Aug 28 08:08:06 EDT 1990 UWS V4.0 (Rev. 164) on DECsystem 3100 and DECstation 2100. Configuration: Server: DECsystem 3100 with 2xRZ55, 24Mb memory and 64Mb swap. Clients: DECstations 2100 diskless with 12Mb memory and 36Mb swap. Connection: Ethernet TCP/IP. Our problem is that we have to reboot the DECstations often more than once a week, because available (free) swap is reduced, but we don't have the problem with the DECsystem. After starting and stopping a number of programs the free swap is reduced and we will get error messages like "not enough core" when starting a new program or malloc error message "can not malloc". If it isn't a swap problem can it be a problem with the display server? We are running Xcfb. Please reply by email.

I'd suggest analyzing the situation after things seem to have become constipated to see where the swap space is being used. DEC X servers have been known to start big and grow over time. You may also have a problem with swap space getting fragmented or having idle/disconnected X sessions lying around sucking up swap space. pstat -s / pstat -p and ps are can be used to try to account for swap space usage... -- George Robbins - now working for, uucp: {uunet|pyramid|rutgers}!cbmvax!grr but no way officially representing: domain: grr@cbmvax.commodore.com Commodore, Engineering Department phone: 215-431-9349 (only by moonlite)
