I could not find any info that said the cause or cure had been identified.
Can anyone fill me in?
For the record:
ccc=# select version();
version
-------------------------------------------------------------
PostgreSQL 7.2.1 on i686-pc-linux-gnu, compiled by GCC 2.96
(1 row)
Also a snip from our postmaster log:

processes
.... followed by a slew of "Postmaster has informed me..." messages.
The process attempting to connect was pgAdminII v1.2.0 .
Postgres had been up for 15 straight days prior to encountering this and
this is the first occurrence in 3 months of otherwise trouble-free up-time.
Any help in responding to this would be appreciated and we're open to
helping further diagnose if the cause is still undetermined.
