Environment: linux + oracle + bb 5.5.1 level3
Does anyone know what causes the "500 - Internal Server Error" messages in
blackboard? They're usually short lived, so if the user waits a few seconds
and hits the reload button, he usually is OK again.
(On linux you can count the errors by means of the following command:
# grep " 500 " /usr/local/blackboard/httpd/logs/access_log | wc -l
We're getting anywhere between 400 to 900 a day.)
I've browsed Blackboard's support pages. They are aware of the problem, but
don't seem to have a clue as to what causes it.
Initially I thought it might be a resource problem, so I bumped up Apache's
MaxClients in httpd.conf, and increased the Oracle listener queue. All to
no avail. I've checked bbuser process limits, system wide maximum number of
tasks, monitored the system, but there are no apparant bottlenecks.
Any ideas?
