Re: [qmailtoaster] SRS - Crashing qmail-send
Hi Jake, Sorry for not responding to this one before - I only recalled the issue with the SRS patch now, as I had to re-install the server again, and found out that the SRS patch for QMail was still the 0.5 version... So - the manual patch to qmail-srs-qt-0.5.patch works - I had a mailserver doing some thousand deliveries per day through it, and the qmail-send restart issue it had was resolved. I would consider that manual change safe. I have not tried to do a higher level patch, as it has not been necessary for me.

For now the server has run without crashing for 4 days, compared to crashing at least once an hour before, more frequently when the load was high. Regards, Lars

All,
I have over the last week been forced to dig into a behavior my server
has been exerting over the last months; namely that of qmail-send
crashing (but automatically restarting) frequently with the error
message alert: unable to switch to queue directory. With it goes all
qmail-remote processes, and the delivery sequence number starts all
over again at 1. Some users report that messages affected end up being
delivered twice. I operate two qmail-toaster servers; and only the
server with SRS enabled is having the problem.
After studying the source I discovered that it was all caused by the
following in the qmail-srs-qt-0.5.patch:
if (chdir(queue) == -1) { log1(alert: unable to switch to queue
directory\n); _exit(111); }
Looking at http://opensource.mco2.net/qmail/srs/ I see that version
0.6 contains a reference to a bug regarding chdir(), and the new code is:
if (chdir(auto_qmail) == -1) { log1(alert: unable to switch to home
directory\n); _exit(111); }
if (chdir(queue) == -1) { log1(alert: unable to switch to queue
directory\n); _exit(111); }
I have not received this behavior before, but I also do not use SRS much.
I plan on updating as many patches to newer/updated versions as I can,
so if you would not mind, keep us appraised on how the new version
works. I would have updated it eventually anyway, but at least this way
I can get some solid feedback on it before releasing it to the masses.
Thanks.
