Apache is back up. Hopefully some post-mortem analysis will give more clues
into the reasons for its falling down. One thing I know is that 'ps'
definitely has a bug which causes it to spin forever once in a blue moon,
and if Apache was waiting (without a timeout) for it to finish, then that
would make sense at midnight during log splitting. The OS may need to be
updated to fix 'ps'.

| Apache (the HTTP server on lugnet.com) fell down a few hours ago at midnight. Apparently a cron job is stuck doing a 'ps' and the reaper hasn't killed it because it's gobbling up CPU cycles. This may or may not be related, but it's a clue. Not sure (...) (26 years ago, 11-Nov-98, to lugnet.admin.general)
