limit youtrack logging

Hi,

on a new youtrack install (on ubuntu, jetty, java 6) I have the problem that youtrack logs an awful lot of information. The sysadmin responsible for this system doesn't want the logs to grow that fast and threatens to shut down youtrack if I don't configure the logging more conservative.

I read in the FAQ that I'm supposed to edit WEB-INF/classes/jetbrains/charisma/main/log4j.xml... In this file i configured the root logger to priority WARN and commented out all individual category settings. Unfortunately this doesn't seem to change anything. Youtrack/Jetty still logs out every http request with INFO level like this:

  2877847 [http request: /_events?window_id=1 [_heart_beat]] INFO jetbrains.mps.webr.runtime.servlet.MainServlet - Start processing request /_events?window_id=1 [_heart_beat]

  2877850 [http request: /_events?window_id=1 [_heart_beat]] INFO jetbrains.mps.webr.runtime.servlet.MainServlet - Finish processing request /_events?window_id=1 [_heart_beat] in 3ms

What can I do? Is this a bug?

Not a single reply yet? Doesn't anyone have the same problem? Do you need more info?
