7.3b1 panic in vacuum

When doing a 'vacuum full verbose analyze' I got the following:

...

This probably means the server terminated abnormally
before or while processing the request.
The connection to the server was lost. Attempting reset: WARNING: Message from PostgreSQL backend:

I'm running it on a sparc/solaris box. There is no core dump.

When rerunning the vacuum on the table it failed on, it seems to work:
