[GENERAL] Incomplete startup packet help needed
Immediately upon starting the server I get an "incomplete startup packet" log message. Just prior there is an "autovacuum launcher started" message. Any thoughts?

We've found that this message is printed in the log if a client makes a TCP connection to the PG server, but sends no traffic. For example it happens with our monitoring system, which checks that it can open a TCP connection to the PG port, then closes it. -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general

I shutdown Tomcat during the restart. Possible a zombie (or hidden/forgotten) process is running though the log indicates local. Had been using pg_admin3 for testing and somehow ended up with a possible zombie process there so maybe... Version 9.0.x - can get the release a little later, running pg_dump at the moment. Still researching/learning but was using WAL shipping and the ship command was failing. In the target directory the most recent WAL files is only ~2MB in size (can't check the pg_xlog directory at the moment). My guess is size quota on target but cannot check at the moment. Turned off WAL archive and restarted the server. Restarted a couple of times until I remembered to shutdown all the other applications. Pg_dump seems to be running OK and was able to execute queries. Was still having difficulty getting my Tomcat software to connect but am unsure if I'm just missing something or what. No obvious messages in either log about that but cannot get back to it until the dump completes. Appreciate any help that can be given. Unfortunately I haven't focused enough attention on Linux (Ubuntu 10.4 LTE) and PostgreSQL administration as I'd like (education and/or professional services). Apparently that is going to change sooner than I had thought.

Since Tomcat wasn't working anyway I decided to just kill the process then restart PostgreSQL...no more spurious error message. Restarted Tomcat and I can now hit my Servlet. Just need to get the base backup and WAL shipping enabled again. Assuming since I disabled it, and just ran a pg_dump while everything was disconnected, that I can basically throw out the shipped WAL files? Still kinda at a loss for root cause and deciding whether there still may be an underlying problem. Thoughts are welcome but I'm likely to seek professional help on this one regardless.

Apparently that is > going to change sooner than I had thought. Alright alot going on. Searching for the error message tends to indicate what others have said, there is something basically pinging the server with 'empty' packets. Given everything you going on right now I would probably wait until the server has attained a more quiescent state before tracking down the culprit. At guess it not something that is server threatening, but worthy of attention. Once the dump is complete and if it is possible, shut down the server. Go through and make sure the programs hitting the server are shut down, for now at least that probably should include the WAL archiving. Start the server up, tail -f the log and then start up the client programs one at a time and see if any of them tickle the error. > > David J. -- Adrian Klaver adrian.kla...@gmail.com -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general

Re: [GENERAL] Incomplete startup packet help needed
We have it too. I think it might be samba related, or just some SNMP software running. I had indentifed the root of the situation some years ago, do not remember it now. It is 100% harmless.
