Ultrix 4.0 swap problem on RISC.

[Bent Nielsen]

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.
Thanks.
