I think it's just a bug in DBD:mysql, I had the same issue and it's a well documented problem. I can't see why SSL would have any effect, it's just a protocol not a driver.

Re: [rt-users] reall odd apache2 crashes with blank pages
yes, i understand that, but you have to take into consideration the fact that someone also mentioned disabling SSL altogether slowed their segfaults, and this is exactly what happened when i tried it as well. before i disabled SSL, i was getting several crashes per day, around 8 or so... constantly. this continued for almost a week. after disabling it, it went steady for a couple days between each segfault, for about another week, until everything finally turned out fine (so far anyways) when i downgraded DBD::mysql.. i haven't seen a segfault in logs since last friday. logic forces me to conclude the problem was not necessarely caused, but most likely exacerbated by the SSL functionality being turned on. -gabe -Original Message- From: Curtis Bruneau [mailto:[EMAIL PROTECTED] Sent: Wednesday, October 08, 2008 9:45 AM To: Gabriel Cadieux; rt-users@lists.bestpractical.com Subject: Re: [rt-users] reall odd apache2 crashes with blank pages I think it's just a bug in DBD:mysql, I had the same issue and it's a well documented problem.

ahh, i get you. indeed, the SSL functionality should work flawlessly now, but we weren't actually *using* it per se, it was just turned on by default. our RT implementation is internal only, and the mysql database is runs on the same host as apache, so there's really no need for it. :) -gabe -Original Message- From: Curtis Bruneau [mailto:[EMAIL PROTECTED] Sent: Wednesday, October 08, 2008 10:03 AM To: Gabriel Cadieux; rt-users@lists.bestpractical.com Subject: Re: [rt-users] reall odd apache2 crashes with blank pages Understood, just saying you should still be able to use SSL without issues with the fixed driver.

Re: [rt-users] reall odd apache2 crashes with blank pages
i have just reviewed the weekend logs for our RT server on apache and have yet to see any more segfaults; this being without downgrading/upgrading DBD::mysql... (i am still at 4.00.7)... i did, however, before leaving on friday, disable the -D SSL flag in my /etc/conf.d/apache2 file, making apache start up without SSL support (we don't need it running on the server as it won't be using https).. i don't know if this had anything to do with it, but i will certainly keep monitoring this issue closely and let everyone know if anything ever happens again, in which case i will try to switch DBD::mysql versions and confirm the fix. thanks to all who participated in the issue so far, as i am sure this affects a lot of people. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of d tbsky Sent: Monday, September 29, 2008 7:44 AM To: Emmanuel Lacour Cc: rt-users@lists.bestpractical.com Subject: Re: [rt-users] reall odd apache2 crashes with blank pages 2008/9/29 Emmanuel Lacour [EMAIL PROTECTED]: On Mon, Sep 29, 2008 at 08:12:30PM +0800, d tbsky wrote: 2008/9/27 Gabriel Cadieux [EMAIL PROTECTED]: i was told it is probably being caused by a bug in the version of DBD::mysql that we have currently installed (mine is 4.00.7, which is the one described in the link below as having this issue). i am still trying to figure out if other stuff is causing it, but on monday i will downgrade to 4.00.5 (gentoo has no ebuild for 4.00.6 for some reason) if the issue is still occuring and let everyone know if this fixes the problem. link: http://bugs.mysql.com/bug.php?id=36810 (thanks to David Chandek-Stark for this information). thanks for the information. our new rt 3.8.1 system is suffered for this problem. i was wondering if mod_perl cause the problem. hope we will hear the good news from you.

[rt-users] reall odd apache2 crashes with blank pages
hi list, is anyone familiar with odd behaviour of RT (i'm using rt3.6.7/apache2) where there are several lines in a row in the apache error log stating segmentation faults and the browser displaying a blank page upon browser refresh or action (such as clicking on a link)? also, when i view source on the blank pages, the code seems to be there! at first i thought this was a browser problem, but then i started to notice the crashing in the error log and saw a bunch of similar (but quite unrelated) problems on google searching, which obviously have nothing to do with RT at all.. most proposed solutions don't apply to me, so i'm stumped.. it seems to happen when i leave the office overnight and come back in the morning (or simply away from my desk for a while), which makes no sense to me because there is no activity on this server while i'm not there (it's on my desk; i'm the only one working on setting it up atm).. i'm 99.% sure it's not caused by hardware problems (ram, etc..) because i thoroughly tested the memory/cpu using memtest86 on the gentoo install cd first, and also ran a full battery of tests on the hard drives and RAID controller card before installing... and the rest of the box runs tip-top, as far as i can tell, there is no reason for apache's children procs to be crashing, so i'm forced to assume something is awry with my RT config, or maybe my apache build? i'm using gentoo with a light (1.5mb) 2.6.26-r1 customized kernel which has everything compiled in for the box (no modules), since the hardware on this server will never be upgraded/changed. as stated before, everything else works great. is there any way for me to find out exactly which system call is causing these segfaults? i'm not too bright when it comes to debugging or coding, so i'm trying to seek help here before trying to dive into tracing stuff w/ gdb etc... :( i really hope someone can help... thanks! (P.S. thanks to everyone on this list for being so nice and helpful so far! i hope i can return the favor in the future when my install is up and groovy :) Gabriel Cadieux Systems Engineer IT Security Analyst STI - Secure Technologies International, Inc.

Re: [rt-users] reall odd apache2 crashes with blank pages
Sounds like what would happen with Scalar::util from rpm on redhat systems. Never used gentoo so I don't know how it's package management works, but you could try re-installing Scalar:util from CPAN.

Re: [rt-users] reall odd apache2 crashes with blank pages
I am having a similar issue with 3.8.1 under Apache 2.2.9, Perl 5.10.0, mod_perl 2.0.4, PHP 5.2.6, mySQL 5.0.45. I verified I am using the newest Scalar::Util module (1.19) as well. The biggest issue it is causing is when it happens while rt-mailgate is attempting to delivery emails and they get stuck in the mail queue. -- Message: 3 Date: Fri, 26 Sep 2008 13:42:58 -0400 From: Drew Barnes [EMAIL PROTECTED] Subject: Re: [rt-users] reall odd apache2 crashes with blank pages To: Gabriel Cadieux [EMAIL PROTECTED] Cc: RT Users Mailing List \(E-mail\) rt-users@lists.bestpractical.com Message-ID: [EMAIL PROTECTED] Content-Type: text/plain; charset=ISO-8859-1; format=flowed Sounds like what would happen with Scalar::util from rpm on redhat systems.

Re: [rt-users] reall odd apache2 crashes with blank pages
i was told it is probably being caused by a bug in the version of DBD::mysql that we have currently installed (mine is 4.00.7, which is the one described in the link below as having this issue). i am still trying to figure out if other stuff is causing it, but on monday i will downgrade to 4.00.5 (gentoo has no ebuild for 4.00.6 for some reason) if the issue is still occuring and let everyone know if this fixes the problem. link: http://bugs.mysql.com/bug.php?id=36810 (thanks to David Chandek-Stark for this information). -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Todd A.
