For your use case, I don't think so.

> Also, the psutil version installed on the system is 3.4.1 while the version mentioned in requirements-stable.txt is 2.2.1. So, I went ahead and downgraded psutil to 2.2.1 by installing an older debian package and the error went away. So, psutil was the cause of the issue. Is it possible to make calendarserver compatible with 3.4.1? The incompatibility issue seems to be becoming a recurring theme :).

I can check on that, but I vaguely recall some reason why we haven't updated to newer psutil.

I think this should be based only on the config value for EnableCardDAV, and possibly also the listener port configuration, depending on how the clients are configured.
