I'm running the server bundle 1.1.0 on a CentOS 5.4 machine, using Java
1.6.0_11-b03. This is on a small home server with perhaps half a dozen
clients accessing on a busy day, and running 7-8 separate calendars. I
access via CalDAV, mostly using Lightning (both Windows and Linux
clients) but occasionally use the web-based client as a control.
At best, this is sluggish to the point of seeming like it doesn't
respond for 30+ minutes at a time. For example, upon starting up
Thunderbird on my work desktop, I will often get only one calendar
responding every 10 minutes or so (I'm subscribed to 6). Sometimes, by
the time all are displayed, one will eventually just "disappear" for a
while, often reappearing later in the day.
I'd like to say that this is solely a client-side problem, but it
appears to be consistent not only across platforms, but within the web
interface as well. Most of the time I cannot even get the web interface
to display properly.
I have debugging on, and so can see that data does seem to be accessed
in the osafsrv.log file. However, there are many occasions where it
seems to crash - I am unable to get any response at all. My ps list
shows that the java command is still running, netstat shows that there
are existing connections, but I can't see anything. The log file shows
either heap space errors (see below) or null pointer exceptions (I can't
find one at the moment).
Any suggestions on what I should look for, or what diagnostics I can
post to aid in diagnosing this?
Thanks in advance,
-Don Levey
