Apache error


#1

I am experiencing a strange problem with Apache (v 1.3.19). I will
intermittently try to go to the main page of RT2 and I receive a page cannot
be displayed error. The following line appears in my apache error_log.

[Fri May 11 15:50:37 2001] [notice] child pid 11549 exit signal Segmentation
fault (11)

I have to refresh 3-4 times to get the login page up. Once I’m in, my
session is fine. I don’t get the error until I try get back into the system
later on. The server is running RH 7.1 and it’s sole purpose is RT. Apache
is not serving out any other pages other than the RT virtual. Also, I am
currently the only user on the system. Any pointers are greatly appreciated.

Thanks.

Thanks for the heads up.
I noticed something like that this morning, though it never affected
my sessions. Are you doing any of the debugging that ivan described
or using Apache::DProf or anything? What RT rev? If you can track it down
any more, a ‘formal’ bug report would be appreciated.

    Thanks,

Jessse,

This is from version 1.3.70 + patches on RH 7.0 (CVS as of Friday
5:00pm GMT)

Apache logs:

[Mon May 14 11:03:48 2001] [notice] child pid 12230 exit signal
Segmentation fault (11)
[Mon May 14 11:04:47 2001] [notice] child pid 12233 exit signal
Segmentation fault (11)
WebRT: Could not create queue: No permission to create queues ()[Mon May
14 15:14:53 2001] [warn] child process 12226 still did not exit, sending
a SIGTERM

First off, this occurs more regularly on ticket creates / updates than
on read only
operations. It sometimes happens at log in as well. It seems to
complete the
ticket creation/update , but doesn’t return any of the webpage when this
happens
(just closes connection). It also appears that any errors do not exit
correctly - see the
third line above …

It used to do it a lot more, but as rt got faster, and I removed all the
unnecessary
Apaches modules which made things a bit bitter again. A race
condition? Timeout?
Also, we haven’t used rt for a while (i.e. overnight) it seems to be a
bit worse for
a while - stuff swapped out excaberating the issue?

Hope this helps.

BTW if you want any more info let me know.

Cheers
Mark

Maybe your cached database connections are timing out? (aka “The Morning
Bug”) http://perl.apache.org/guide/databases.html#The_Morning_Bug

Try increasing MySQL’s timeout as specified in that URL.On Mon, May 14, 2001 at 04:08:02PM +0100, Mark Vevers wrote:
