Re: [Dbmail-dev] Troubles: rev-1996
I've just checked in some changes in the server code. SIGHUPs are now handled correctly. Oleg and Aaron, please test and confirm if you don't mind.

Reading the code here, and this is Paul's neck of the woods, so I may well be misunderstanding things, is that at the bottom of the loop the socket is closed, then at the top of the loop the socket is reopened and another child is forked and waited on. If that socket could not be opened, then the process dies (see server.c, dm_bind_and_listen). So I think that it's the parent process here that's somehow lost ownership of the socket and so the parent dies but the children stick around (because their parent is now 1? or is that a sympton?)

Re: [Dbmail-dev] Troubles: rev-1996 and 1997
Paul, Reading from imapd.c, through server.c, and to pool.c, it looks like the process path is like this: imapd.c: parent process (root) imapd.c: child process (nobody) server.c, pool.c: manage more children (more nobodies) When you send a HUP to the parent, it does this: imapd.c: parent process - Receive the HUP, tell child to restart imapd.c: child process - Told to restart, kill the children server.c, pool.c: told to stop, children are killed. Then this happens: imapd.c: parent process (root) imapd.c: child process (nobody) -- tries to get a new socket, can't! Is that first fork needed to establish the dropped privs before forking each of the children in the pool? It would make sense to have the first child simply terminate when it gets a signal, and then the top level parent restarts everything...

Every time the function is called, it will reap the memory from the previous call. Exactly the same fix you made for db_query ;-) Aaron
[Dbmail-dev] [DBMail 0000306]: the processes spawn infitnetly until they crash the machine
The following issue has been SUBMITTED. == http://www.dbmail.org/mantis/view.php?id=306 == Reported By:variable Assigned To: == Project:DBMail Issue ID: 306 Category: General Reproducibility:always Severity: crash Priority: normal Status: new == Date Submitted: 28-Feb-06 23:08 CET Last Modified: 28-Feb-06 23:08 CET == Summary:the processes spawn infitnetly until they crash the machine Description: Both on 2.0.7 and 2.0.9 all 3 processes will spawn indefinatly until the machine crashes, I found that if you set the TRACE_LEVEL=5 it will solve the problem, and have been running my production server like this for http://www.dbmail.org/mantis/view.php?id=6#2 months now. Also these open processes keep opening connections to pgsql and quickly use all the connections for pgsql. == Issue History Date Modified Username FieldChange == 28-Feb-06 23:08 variable New Issue ==

This is the malloc for () keys in the command parser I am talking about. Oh. Hrmm... I'll try to take a look at it tonight. I think the lazy/stupid approach will be to change that global the_args array to be a static variable inside of the build_args function. Every time the function is called, it will reap the memory from the previous call. Exactly the same fix you made for db_query ;-) That was the issue, you can't reap/free the memory for each allocation because you loose the pointer refernece, it leaks because when the the_args array is free'ed after use you only free the ref to the main allocation. I belive the correct solution would be to change it to a resizeing realloc or somthing of that nature so that when freeing the allocated args it free's all the memory in the buffer because it was realloced each time to point to the whole thing...etc. -leif Aaron ___ Dbmail-dev mailing list Dbmail-dev@dbmail.org http://twister.fastxs.net/mailman/listinfo/dbmail-dev
