[rt-users] Hanging Login Page (ModPerl2, HTTPD, Oracle, RHEL5)

[Charles Kugelman]

Update on this:

 

I've updated httpd, httpd-devel, mod_perl, mod_ssl to the latest
version. Problem still exists.

 

One additional thing to note is that this is running as a virtual
machine (on ESX) with 1GB of memory allocated.

Greetings RT Gurus!

 

 

--Problem--

Every morning when I sit down at my desk and point my browser to RT, it
hangs when the login page should be displayed. Usually I've just
performed a "service httpd restart" to resolve the problem. This
morning, I just let it sit and load for in excess of 20 minutes, and the
page finally appeared, after which RT seemed to be performing fine -
even if I restart my browser and head back to the logon page. This did
happen in the middle of the day yesterday as well, to which I restarted
httpd, as normal. This, obviously, won't work for production (which we
plan on this system being shortly). I'm sending this message in the hope
that someone can assist me with this problem.

 

 

--Relevant Info--

- RT Version: 3.8.2

- HTTPD Package (RPM): httpd-2.2.3-6.el5

- Mod_Perl Package (RPM): mod_perl-2.0.2-6.1

- Perl Package (RPM): perl-5.8.8-18.el5 

- OS: RedHat Enterprise Linux 5

- Oracle Client: 10.2, Instant Client

- Oracle Server (remote server): 11g

- Mail Package (RPM): postfix-2.3.3-2

- I've done some digging in the archives and found the post by Dirk Pape
(subject: Performance-Bug in SelfService when updated from 3.6.1 to
3.6.3, date: Jan 22, 2007, 11:39 PM) and the issue seems to be very
close to what I'm seeing. But the resolution that Dirk used doesn't seem
to apply to the current version of RT, as "@roles => ('Watcher')" is
already set in the html/SelfService/Elements/MyRequests file by default.
And my seems to be with the logon page.

- I have added the following lines to httpd.conf in order to force
http:// requests to use https:// (don't know if this may have some sort
of impact).

 

          RewriteEngine On

RewriteCond %{HTTPS} off

RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}

 

- Could the way Postfix is configured be causing this problem? The
problem seemed to come into play when I started working on the mail
components.

 

 

--Non-Standard Features Being Used--

- SSL (on the front end)

- RT External Auth Plugin (authenticating successfully against AD)

 

 

--What Seem to be Relevant Error Log Outputs--

- /var/log/httpd/access_log: The error below seems to be appearing quite
frequenetly. I'm not sure if it's related or not, but doesn't look good.


 

(RTHOST) - - [03/Apr/2009:09:51:57 -0400] "POST
/REST/1.0/NoAuth/mail-gateway HTTP/1.1" 302 333 "-" "libwww-perl/5.805"

 

- None of the other logs that I've checked (httpd error_log, rt log)
appear to have anything of relevance to this problem. 

 

 

Thanks in advance for any assistance you may be able to offer.
