I hate to post as vague a description as this, but I don't think the
devil is in the details this time. I may be wrong ...
This project is running 7.3.2 on a RedHat 9 system. We plan to
upgrade in a few weeks to Fedora Core and Postgres 8, so maybe this
problem is not worth wasting too much time on, right now.
This is a SOAP server, Apache with mod_perl, connecting to Postgres
via DBI/DBD::Pg. Sometimes it gets in a mood, for want of a better
term, where a specific SQL statement fails with the good ole message
"server closed the connection unexpectedly". It will fail like this
for several hours, then suddenly start working again. The SQL that it
fails on works perfectly in psql; it always returns the exact data
expected. It's a small table of perhaps a dozen lines, and does not
change very often. I would suspect hardware except that a new machine
behaves just the same.
One of the puzzles is that nothing shows up in the log. The log is
configured thusly:
server_min_messages = notice
client_min_messages = notice
log_min_error_statement = error
And yet only the only messages that show up are start and stop. I
changed log_min_error_statement to notice like the others, and it
hasn't failed since, but I doubt this is the cause, because it has
gone thru these mood swings before without having changed the log
level. It's not the soap server disconnecting from the SOAP client,
because the server continues to log things.
Did 7.3.2 have any problems that might cause random disconnects, or
diconnects for some obscure but documented reason? Google found some,
but none of them apply here, as far as I can tell.
Or are there useful changes to logging that might track this down?
Strace generated about 50MB of log file, too much for me!
