Hi,
Our production server is running PostgreSQL 8.2.22 and pgpool-II-2.0.1 in
CentOS5.2 64-bit arch. We're running all our application software stack
(Tomcat, PostgreSQL, pgpool, etc.) in the same server.
Yesterday, we faced a weird behavior in our production server. Our
application was totally hung up and eventually application users were not
able to access the system completely. This happened twice. So we end up
restarting our complete application service. On checking PostgreSQL log,
there were "unexpected EOF on client connection" errors. But when I also
checked pgpool log at the same time as these exceptions in PostgreSQL log, I
could see new type of errors appearing in pgpool log. I've pasted below
only pgpool log statements containing ERROR as its debug level.
>From the ERROR statements, I can see 4 types of exceptions being raised:
1) pool_process_query: kind is 0!
2) ProcessFrontendResponse: failed to read kind from frontend.
fronend abnormally exited
3) pool_flush_it: write failed (Broken pipe) offset: 0 wlen: xxx
4) pool_read: read failed (Connection reset by peer)
What are the root cause of these exceptions and what is the severity level
of it? How do I prevent/fix these exceptions?
