>Environment:
Box runs mainly sendmail, majordomo & mhonarc. Occasional bursts of traffic
to 20,000+ list addresses or processes growing to 200MB+, deliberately
throttled with old, slow disks and 1542 controller. Problem may also be
occuring on big squid boxes (similar symptoms), but owners are linux
weenies and haven't a clue about ddb. Note that crash dump doesn't work.
