Subject Re: strange error messages in tomcat log and mod_jk2 log
Date Mon, 15 Dec 2003 08:30:35 GMT

thanx for your reply. hm. it's a very strange thing.

some questions:

are you running your application under heavy load?
are the responses very big in size?
do you use the apache2/mod_jk2/tomcat4 config on a windows nt4 box?
does a dialogbox appear on the server with an error message stateing
that the apache.exe caused an internal error, and after pressing Ok the
apache2 server continues to run?

maybe we can find some similarities.

we have no idea what direction to look for, and the problem is very
critical because a very big application is crashing every few minutes,
so a production environment couldn't be setup... :-((

thx, Chris

Ein Physiker, ein Mathematiker und ein Windows-Programmierer fahren in
einem Auto, als dieses plötzlich der Geist aufgibt. Der Physiker
schlägt vor, mal das Benzin zu kontrollieren.  Der Mathematiker sagt,
er verstehe nicht viel von Autos, aber man solle mal das Kühlwasser
überprüfen. Der Windows-Programmierer meint, er würde zuerst alle
Fenster schließen, aussteigen, erneut einsteigen und dann alle
Fenster wieder öffnen.
