Problem : truss process

seeing some problems on a Sun Iplanet Calendar server, seeing the cshttpd process hand and users cannot login, then most of the time
it comes back without restarting it, when doing a truss on the process I see these errors when you cannot login via the web http login and
when there is no problem with login I don’t see these errors in the truss, can anyone give any comments or info on to what these errors
mean, already worked worked with Sun a lot on these and haven’t go very far, a few patches that seemed to help but problem keeps coming back.

Thanks

Solution: truss process

Any error messages in /var/adm/messages?

What was you doing when it hang, it is repeatable?

if it hangs on users attemp login, you can try to set “service.admin.sessiontimeout ” in the ics.conf file to a lower value.  the default is 1800s (30 min), try to  set it to 10 min to see if it can help.
