Re: [rt-users] RT4 - mod_perl problem with apache2
Good morning,
we had the same problem here, disabling the GPG Stuff made the segfaults go
away.

Hi guys,
I've googled it, some people also have this problem, but no solutions
were provided by anyone.
The problem is:

The way of restarting apache which doesn't cause error to be thrown is
just:
/etc/init.d/apache2 stop; /etc/init.d/apache2 start
but it's, well, inelegant.
The issue is probably related to Plack.
Unfortunately, it's difficult to try replicating without a
perl/apache/mod_perl2/plack version list

Hello, I'm having a VERY similar problem here. Using rt-4.0.2 and
debian squeeze 6.0.3, which comes with apache 2.2.16-6+squeeze4,
mod_perl 2.0.4-7, perl 5.10.1-17squeeze2 and from what i can tell
Plack 0.9984 which i just installed from CPAN. This is my rt config in
apache:
Location /rt
Order allow,deny
Allow from all
SetHandler perl-script
PerlResponseHandler Plack::Handler::Apache2
PerlSetVar psgi_app /opt/rt4/sbin/rt-server
/Location
Perl
use Plack::Handler::Apache2;
Plack::Handler::Apache2-preload(/opt/rt4/sbin/rt-server);
/Perl
If I don't comment this
Plack::Handler::Apache2-preload(/opt/rt4/sbin/rt-server);, I
can't do the following without getting a segmentation fault, even if
apache is not running:
root@blazar:~# export APACHE_RUN_USER=www-data
root@blazar:~# export APACHE_RUN_GROUP=www-data
root@blazar:~# export APACHE_PID_FILE=/var/run/apache2.pid
root@blazar:~# export APACHE_RUN_DIR=/var/run/apache2
root@blazar:~# export APACHE_LOCK_DIR=/var/lock/apache2
root@blazar:~# export APACHE_LOG_DIR=/var/log/apache2
root@blazar:~#
root@blazar:~#
root@blazar:~# apache2 -t
Syntax OK
Segmentation fault
That last sequence of commands is something that apache2ctl do almost
every time you run it, and at least in Debian apache2ctl is used in a
lot of places, from startup to shutdown to log rotation. RT4 works
correctly from what i can tell as long as i don't comment the preload
line, but then again apache2ctl breaks down and with it, other things
follow.
The only error i can see in my syslog every time i run 'apache -t' is
the following:
Oct 30 21:44:22 blazar kernel: [4016030.401140] apache2[17570]:
segfault at 7fa814baa640 ip 7fa814baa640 sp 7d346fc8 error
14 in libnss_files-2.11.2.so[7fa817aaf000+b000]
As a side note, I do have a working RT4 installation in debian
squeeze, but this was installed some time ago and it was the rt-4.0.0
tarball and I guess some of the CPAN modules are older too.
Any help would be really appreciated. Thanks a lot.

If a user has a right, through either an individual right or a group right, then they will have that right. I basically avoid using individual user rights altogether; on anything beyond a very small setup it becomes unmanageable. I always create an admincc group for each queue, for example, and give users rights to that queue by changing their group membership.

While children occasionally spike to a high CPU usage, if that's been spinning for a while at 93% then something is wrong. You'll want to use your logs to find out what the apache child is doing. You might be able to divine it from access logs and seeing what pages are being loaded.

Re: [rt-users] Custom per queue views
Thanks for the response! I've just implemented the below for a few of the more common fields, however, there's still several custom fields that are very queue specific so if implemented as below it will result in the Queue Summary being full of empty fields for queues where that custom field is not defined. I do think this would be a fantastic capability for RT in being able to define a default view based off the Query Builder. In the mean time, are there perhaps any callbacks that could be taken advantage of to emulate such a capability? I've taken a look but haven't found any that seemed to be a sensible match for what I'm trying to achieve. Thanks again for the advice.
