[CalendarServer-dev] Problem running calendarserver 6.2 in Debian

[Rahul Amaram]

Hi,
I am the Debian maintainer for calendarserver. For calendarserver 6.2, I 
have the new binaries built, including a new package for twext. But when 
I run it, I get the error:

# caldavd -L

Attaching the caldavd.plist file that I am using. The postgres database 
is created and pre-populated with the schema. Could you provide any 
pointers on why this is occurring?

On a side note, if I run using the normal way i.e. ./bin/run -n, then it 
starts properly. So, not sure what is the issue here.

Thanks,
Rahul.
