i have a Problem with the Webdav Interface to the Calendar. If a Calendar has much entries (more than 600), i cant access it via http://OX-SERVER/servlet/webdav.ical because of a timeout (i raised the timeout already to 300 seconds). The Server-Config is ok, because i can access the Calendar if there are fewer entries.
Is there a way to increase Performance of the Webdav Interface or is there a parameter to access only Calendar-Data after a defined date?

OS: Open SuSE 11.0
OX: Open XChange 6.8.1

Log entrie:
INFO: AJP Listener "AJPListener-0000078" exceeds max. running time of 300000msec -> Processing time: 308995msec

Thanks in advance!
