#37120 [Fbk->Opn]: mod_php5 + apache2 + mail() = hung process

ID: 37120 User updated by: brlcad at mac dot com Reported By: brlcad at mac dot com -Status: Feedback +Status: Open Bug Type: Apache2 related Operating System: FreeBSD 5.2.1 PHP Version: 5.1.2 New Comment: <whine>Yes, but such a pain in the arse to set up as it's a live production system...where's the magical intuition and devine insight??</whine> :-) I'll see if I can get an updated backtrace. Cheers!

A gdb backtrace is worth of thousand words. ------------------------------------------------------------------------ [2007-02-21 23:10:23] brlcad at mac dot com For what it's worth, I don't believe the problem (at least as I've reported) is so much related to the previous poster's freebsd bug report link. It may very well be specific to FreeBSD and even this version of the OS, but it also seems to be rather isolated to PHP5. I've tested with other Apache modules and none of them have trouble sending mail like PHP seems to be having, and sending mail directly works like a charm. What's perhaps useful to note, and that I perhaps didn't emphasize enough, is that with version 5.1.2 it would just hang the httpd process and the web page request would simply never terminate. Now with whatever change was made in mail () since 5.2.1, it crashes the httpd. It's curious that httpd is dying via signal 6 (SIGABRT, abort()) and not a usual segv or bus error, etc. ------------------------------------------------------------------------ [2007-02-21 21:53:48] tony2001@php.net Doesn't look like PHP problem to me, more like FreeBSD bug. ------------------------------------------------------------------------ [2007-02-21 21:20:32] brlcad at mac dot com To hopefully revive this issue, I'm using the latest release 5.2.1 version of php (from FreeBSD ports), with the same setup and constraints as mentioned before in this report and still see the same crashes (httpd exits on signal 6) during a mail() call from mod_php5. ------------------------------------------------------------------------ [2006-08-10 21:42:15] spike at indra dot com I am seeing the same behavor in 4.4.3. I wrote a script to replace sendmail and confirmed that the data is being written to the pipe, but that the pipe is not being closed. I then stuck debuging statements in mail.c and found the it hangs on pclose(). Again, this is only in apache, not from the command line.
