Posted by Bob Powell on 01/07/05 03:32 PM

Hello everyone,

I have just upgrade to OpenACS 5.1.2, AolServer 4.0.8 and Postgres 7.4.6. These are all running on DEBIAN Linux.

My AOL server intermittently crashes without warning. The current fix is to just restart the process and continue on.

I have the verbosity turned up all the way in an attempt to determine what the cause is. The last messages in my error file before the restart messages is:

Error: ad_monitor_top: top could not be run - TERM environment variable not set.

Warning: nsopenssl (minerva): SSL read interrupted: Connection reset by peer.

Those are the last two messages before the AOL/4.0.8 starting message.

Anyone else experience this kind of thing? Any help is greatly appreciated.

One thing to check is your stacksize.

If it is less then below try increasing it:

ns_param stacksize [expr 512 * 1024]

You are using SSL. Please use AOLserver 4.09 with the latest nsopenssl. Previous versions have serious memory leaks. The latest one might have only one :).
