- I get this problem. I think it's to do with available swap, as I usually
- see it when I have a zillion DM windows open on the other side (I like the
- ability to make window groups invisible; who said VUE invented workspaces?)
- and lots of fancy X as well.
-
- From what I've been able to trace down, when a client asks the X server for
- a new font, the server forks off a couple programs to get it. Since apollo's
- don't seem to have COW fork(), this means the entire X server gets duplicated
- temporarily. If you haven't enough space, the popen fails and the font can't
- be found.
-
- Several months ago somebody mentioned they had hacked up a replacement popen
- which invoked another process without forking. Somewhere way down on my list
- of things to do is to try this solution to see if it helps the font problem.
-
- About xlsfonts -- I think it usually just looks at a list it maintains, without
- trying to actually open the fonts. If you use the "verbose" or "long" flag, I
- think it tries to open each font to get the additional information, and this
- would demonstrate any problem.
-
- In addition to just running more and more processes (which is how I run
- into trouble), look for memory leaks, ever-growing files in /tmp, and pads
- that get long. (Infinite scrollback *does* have a cost! ;-) ) All these
- eat up the same disk space that is used for swap.
