Hello, I encountered a problem with a pgpool installation. Pgpool failed and detached a backend, but I don't know the reason because that particular pgpool server is not writing to its log (problem with cronolog, and I can't restart pgpool since its a live system).
What I did find was a suspicious message in the postgres log of the failed backend. Here are the relevant lines of the log: 2009-12-23 15:07:20 CLST, sess LOG: duration: 39.809 ms statement: EXECUTE <unnamed> [PREPARE: COMMIT] 2009-12-23 15:07:20 CLST, sess FATAL: invalid frontend message type 4 2009-12-23 15:07:20 CLST, sess LOG: unexpected EOF on client connection 2009-12-23 15:07:20 CLST, sess LOG: unexpected EOF on client connection 2009-12-23 15:07:20 CLST, sess LOG: unexpected EOF on client connection 2009-12-23 15:07:20 CLST, sess LOG: unexpected EOF on client connection 2009-12-23 15:07:20 CLST, sess LOG: unexpected EOF on client connection 2009-12-23 15:07:20 CLST, sess LOG: unexpected EOF on client connection 2009-12-23 15:07:20 CLST, sess LOG: unexpected EOF on client connection Since this happened at the same time as the failing of the backend I'm assuming this condition made postgres close the connection to pgpool and so triggered the failing and detaching of the backend. Does anybody know what message type 4 is ?
