The best guess I have is that this is a failure in Solaris' syslog.
There is certainly no such message anywhere in the Postgres backend
code. Try changing your syslog setting to 0 (log only to stderr)
and see if logging to a plain file works better.
BTW, PG 7.3.4 is pretty darn old, you really ought to update.
