Folks,
Yesterday I tried running the math/abs package on my 1.4.1 AlphaPC, and
it locked up hard with an:
WARNING: mclpool limit reached; increase NMBCLUSTERS
every minute on the console. Trying to kill abs from ddb resulted in a
"no such process" message. Does the ddb kill command work on the alpha?
From a ps alx from the crash dump:
UID PID PPID CPU PRI NI VSZ RSS WCHAN STAT TT TIME COMMAND
7006 18205 0 36 72 4 2904 0 - RN q0 28:44.24 (abs)
and ps aux:
USER PID %CPU %MEM VSZ RSS TT STAT STARTED TIME COMMAND
simonb 18205 99.0 0.0 2904 0 q0 RN 5:57PM 28:44.24 (abs)
and the only funny looking lines (to my eyes) from vmstat -m are:

There have been some changes to uipc_mbuf.c since 1.4.1, but I don't
know if they'd fix the above problem. For now, I've got
options NMBCLUSTERS=1024
but I've not tried running abs again. This is my main home box, and I'd
like to keep it running :-)
Simon.
