Hi<div><br></div><div>I am running xemacs from the carbon2 branch on my mac. I find that after a few hours of inactivity, xemacs takes up a lot of cpu constantly, using about 60-80% of the cpu (and firefox the remaining). I had one such xemacs instance under gdb, but I know neither xemacs internals nor carbon. So any help getting to the root of this problem will be useful. I can help debug the problem when it happens next, if I am given clues about where to look for what.</div>
<div><br></div><div>I ran dapptrace (dtrace script for tracing function calls) and I have put the output here:</div><div><br></div><div><a href="http://mirthmakers.com/code/xemacs-dapptrace.txt">http://mirthmakers.com/code/xemacs-dapptrace.txt</a></div>
<div><br></div><div>This file is really large, as I turned on all the options for dapptrace, just to get as much data as possible (may be too much though, now that I look at the output).</div><div><br></div><div>Here is the gdb backtrace, in case this is useful for someone. It just does this all the time.</div>
