CPU: DECstation 3100 OS: Ultrix 3.1 Display: 19" color Server: X11R4 MIT (Xcfbpmax) WM: mwm / twm The X11R4 server grew to an 11K virtual image over 4 days. Leaks supposedly created by Epoch not releasing resources (fonts, maybe). Other clients (xman, for example) cause the server to grow. I was under the impression that resources allocated for a specific client are released when the client exits. This doesn't appear to be happening. There has been previous mention here of memory leaks. I previously used an X11R3 server from DEC, and never had any trouble with memory. What is the experience of others with R4? ...anon... anon@eecs.umich.edu

Within 24 hours of upgrading we'd run out of communal swap space - something we never did with R3. As far as we could tell the number and type of clients being used were similar to that under R3. As an attempt to get around this we've set xdm up to terminate the server rather than reset it. This appears to have helped for the moment (although we're wondering if we'll have to revert to xinit when we upgrade other clusters with less swap space).

On a Sun 386i/150 (SunOS 4.0.2, 8 Meg, 16 Meg swap), I've seen Xsun grow to
over 2 meg in about fifteen minutes of playing with xgc. I really noticed it
when I tried to run a couple of new processes, and got an "out of memory"
message. Did a ps, and Xsun had grown to about 2.4 MB. The system had been
up for less than 24 (probably less than 10) hours, and I hadn't noticed any
problems earlier. (I do an occassional ps just to watch memory usage, since
I know that there's a problem.)
