        HINT:  This error usually means that PostgreSQL's request for a shared memory segment exceeded available memory or swap space. To reduce the request size (currently 1818624 bytes), reduce PostgreSQL's shared_buffers parameter (currently 50) and/or its max_connections parameter (currently 10).
                The PostgreSQL documentation contains more information about shared memory configuration.

Hello,

Different OSes have different defaults for shared memory settings. Here's a link to the postgres documentation around shared memory and how it is configured on various OSes: http://www.postgresql.org/docs/9.0/interactive/kernel-resources.html

I don't have any FreeBSD stuff set up at the moment so I can't test this, but you should be able to raise shmall, shmmax, and semmap as shown in the documentation. You may have to experiment a bit to find suitable values. Please let us know what works for you.

Since changing these settings requires superuser access, this isn't something that Calendar Server could or should do for you automatically. The end result of this could be that we simply improve our documentation to make sure users know to set shared memory settings appropriately.

Cheers, -dre

Hrm, so that's not usually the sort of this we can adjust unless we are root, so I don't know that we can fix this in the run script; developers may need to do this on their own.

Perhaps, though, we can detect it and emit some instructional info, like when there is no caldavd-dev.plist.
