Hi, I’m Yoann. It’s my first message here so a little brief about me. I’m a OS X Server System Administrator and Trainer, actually working on a FreeBSD based setup for a simple services provider infrastructure. I plan to use the calenderserver project for CalDAV and CardDAV instead of the easy to use SOGo to run a server more close as possible to the RFCs. I successfully setup the 4.2 release with a LDAP and a PostgreSQL backend on a FreeBSD 9.1 64 bits processor. It was a pain because the 4.2 didn’t handle well the 64 bits socket descriptors but I’ve add some fixes for that. That was the same with de dependencies, a lot of things seems to be unstable on 64bits, so I install the requirements by my own and run it with a -nr to don’t use built-in deps. By the way, the behavior to install all deps in .. fold is really unusual and put a big mess… But what ever. It seems to look like a working config at the end. I can run the server, authenticate my self, if I enable the principals navigation I can see all my users, I can connect iCal and use it. Well, it’s work. But, after some times, the server seems to by buggy, I start to make time outs for request, or for opening sockets, or sometime it rework again… Really random behavior and not at lot of interesting things in logs… To have a idea, all my services, caldavd included are under nagios monitoring, I get something like 20 alerts per day about CalendarServer in a critical state… Anyone can give me a clue about what to look ? What can be the source of the problem ? How to troubleshooting it ? Best regards, Yoann.
