LyX-1.2.2 and zombie processes (MacOS 10.2.3)

[Ronald Florence]

LyX-1.2.2 on MacOS 10.2.3 seems to leave zombies in the process table -- enough of them over time to exhaust the available process slots. (LyX was compiled with the gcc-3.1, xforms-1.0-1.)

Here's a glimpse of ps -aux after LyX has been running only a short while:

ron 3332 2.7 0.4 11332 4620 ?? S 11:29AM 0:15.11 lyx /Users/ron/Documents/lng/lng.lyx
root 3336 0.0 0.0 0 0 con- Z 31Dec69 0:00.00 (lyx)
root 3337 0.0 0.0 0 0 con- Z 31Dec69 0:00.00 (lyx)
root 3354 0.0 0.0 0 0 con- Z 31Dec69 0:00.00 (lyx)

I believe I noticed the same phenomenon with LyX-1.2.1, and am not sure whether it is worse with 1.2.2. I have no idea what these zombies are, why they are owned by root, or why they have the bizarre date/time. They die with LyX. On at least one occasion, when LyX had been running for a few days, I had to kill LyX to free slots in the process table.

Is there a fix, or anything I can do to help debug the problem? Thanks,
