We are running apache2 on OES linux with GW webpublisher and webaccess.

Recently, every day or so, Apache just stops responding. It is still running, but browsers time out when trying to connect and webaccess and webpublisher quit.

If I issue the command rcapache2 restart everything is up and fine again. Webaccess and webpublisher both work as well as the web server.

When the server does stop, here are the lines in the error log. Notice the server quit at 8:45 and did not serve any more pages until I restarted it at 11:46.

Can someone give me a hint as to what is going on? Are the mod_mono errors the cause of the problem or a result after something else stopped the server.

Thanks for any help!
