Hi, I've been working on a problem which I thought was a postgres driver problem, but now I'm not so sure. I put a bunch of debug statements in the driver functions. I've grepped the debugs for db_init|db_close|connect_db|disconnect_db and here is what I have: -----------cut------------ Mar 1 23:59:49 rave ser[1803]: db_init(): sql://USER:PASSWORD@humpty.august.net:5432/THEDBNAME Mar 1 23:59:49 rave ser[1803]: connect_db(): here we go Mar 1 23:59:49 rave ser[1803]: connect_db(): we are connected /tmp/debug.1803.out Mar 1 23:59:49 rave ser[1804]: db_close(): disconnect_db() Mar 1 23:59:49 rave ser[1804]: disconnect_db(): entry Mar 1 23:59:49 rave ser[1804]: disconnect_db(): PQfinish() Mar 1 23:59:49 rave ser[1804]: db_close(): free self Mar 1 23:59:49 rave ser[1804]: db_init(): sql://USER:PASSWORD@humpty.august.net:5432/THEDBNAME Mar 1 23:59:49 rave ser[1804]: connect_db(): here we go Mar 1 23:59:49 rave ser[1805]: db_close(): disconnect_db() Mar 1 23:59:49 rave ser[1805]: disconnect_db(): entry Mar 1 23:59:49 rave ser[1805]: disconnect_db(): PQfinish() Mar 1 23:59:49 rave ser[1805]: db_close(): free self Mar 1 23:59:49 rave ser[1805]: db_init(): sql://USER:PASSWORD@humpty.august.net:5432/THEDBNAME Mar 1 23:59:49 rave ser[1805]: connect_db(): here we go Mar 1 23:59:49 rave ser[1806]: db_close(): disconnect_db() Mar 1 23:59:49 rave ser[1806]: disconnect_db(): entry Mar 1 23:59:49 rave ser[1806]: disconnect_db(): PQfinish() Mar 1 23:59:49 rave ser[1806]: db_close(): free self Mar 1 23:59:49 rave ser[1804]: connect_db(): we are connected /tmp/debug.1804.out Mar 1 23:59:49 rave ser[1806]: db_init(): sql://USER:PASSWORD@humpty.august.net:5432/THEDBNAME Mar 1 23:59:49 rave ser[1804]: db_init(): sql://USER:PASSWORD@humpty.august.net:5432/THEDBNAME Mar 1 23:59:49 rave ser[1806]: connect_db(): here we go Mar 1 23:59:49 rave ser[1804]: connect_db(): here we go Mar 1 23:59:49 rave ser[1805]: connect_db(): we are connected /tmp/debug.1805.out Mar 1 23:59:49 rave ser[1805]: db_init(): sql://USER:PASSWORD@humpty.august.net:5432/THEDBNAME Mar 1 23:59:49 rave ser[1805]: connect_db(): here we go Mar 1 23:59:49 rave ser[1804]: connect_db(): we are connected /tmp/debug.1804.out Mar 1 23:59:50 rave ser[1805]: connect_db(): we are connected /tmp/debug.1805.out Mar 1 23:59:50 rave ser[1806]: connect_db(): we are connected /tmp/debug.1806.out Mar 1 23:59:50 rave ser[1806]: db_init(): sql://USER:PASSWORD@humpty.august.net:5432/THEDBNAME Mar 1 23:59:50 rave ser[1806]: connect_db(): here we go Mar 1 23:59:50 rave ser[1806]: connect_db(): we are connected /tmp/debug.1806.out Mar 2 00:00:50 rave ser[1807]: begin_transaction(): BEGIN error server closed the connection unexpectedly ^IThis probably means the server terminated abnormally ^Ibefore or while processing the request. -----------------cut-------------- The current processes that are running are: [root@rave sip_router]# ps -ax | grep ser 30060 ?

I think linux does threads with processes, so am I seeing 2 'processes' with 3 threads per process??? 2) the debug output has the process ID and the action being performed. Either it is way out of order, or the postgres db driver is being asked to do things out of order. 3) Why is there all of the db_init(), db_close() stuff?? All of this stuff happens in the first second on startup. Surely that many opens and closes aren't really needed are they? 4) select statements seem to happen in one thread, and insert/delete statements seem to happen in another thread. What is that about? ---greg Greg Fausak
