Good morning,
Wer are running the following configuration:
Apache 2.0.58 with mod_jk2
Tomcat 5.5.7
This morning we had to stop our system and remove a 1.5
GigaByte-Errorlogfile of
our apache installation because our filesystem capacity had been reached.
The apache-errorlog-file never used to grow that much before. A look
into the huge
logfile showed something like this:

My first impression is that the loglevel of mod_jk2 was set to notice,
but our production
department says they did not change the mod_jk2-configuration. At this
moment, the workers2.properties
says that the mod_jk-loglevel is set to debug.
As I don't know mod_jk internal, maybe some tomcat users have an idea
what happened last night?
Is there some flaw in mod_jk making the loglevel to switch under certain
circumstances?
Is the notice-level part of the debug-loglevel of mod_jk and there
occured some problem/situation
which made mod_jk to log these endless "received"-messages?
Might the other department be wrong about not having changed the
loglevel of mod_jk? Maybe there
is some indirect effect to mod_jk when you change some other setting?
Thank you in advance for any help,
