Subject: the old FIN_WAIT_2 problem.
Customer ID: N3668
Hello,
We are running BSD/OS 3.0 and Apache 1.2b7.
We believe we are experiencing the same problem that patch K210-027 had
supposedly fixed. Could you check this out?
The symptom is: the apache server suddenly hangs for varying periods of
times. We have a cron job that checks it and dumps the following info
when it happens (note: we have two separate Apache installations, one on
204.19.108.3:80 and the others on the 207.253.6.0 net).
