Hi,

Postgres is part of the openSource repository DSpace which we are running here 
at ANU. I upgraded from 7.4 to 7.4.1 on 17 January. Today (21/1) it appears 
that either the number of connections has been reached (which is not possible 
on my local install) or the database itself has locked up. Postmaster was 
restarted on 20/1 so the problemt has taken 2 days to surface. I have not had 
a chance to look much deeper into the problem as I don't expect to get time 
to investigate until next week.

The log output postgres returned is as follows:
  FATAL: the database system is shutting down

The application log is as follows:

Note that postgres is the only thing that has changed, no other software has 
been updated. This did not occur under 7.4

A secondary issue is that postmaster will not shut down properly under 7.4.1, 
I always have to use the "fast" shutdown mode. Has anything changed in the 
connection handling, as if connections are not being released this could 
easily cause the first problem? Again, this appears peculiar to 7.4.1.

Thanks.

Scott.
