I can't really promise that your local changes to RT will work perfectly across an upgrade without auditing your code. If that's the sort of thing you're looking for, please contact me off list and we'll see about getting some sort of contract set up.

Re: [rt-users] RT : Apache Resource Usage
Hello Jesse Yeah your right infact we have more than 30 concurrently users using RT and I can't bring the number of Fastcgi processes less than 30. So I want to make sure that will recent version of RT i.e. 3.8 will work well as far as memory allocation is concerned and second thing I want to know is, Is it possible to upgrade my RT on production as well and preserving the customization and scrips we have placed over there. If not then what's the way to achieve this backup stuff on application side and to upgrade it also. Waiting for a valuable answer from your side.

I know that recent 3.8 releases include fixes for a number of memory leaks we've managed to track down. 30 concurrent FastCGI processes suggests that you need to be able to handle 30 people making requests of RT at exactly the same instant. If that's true, you'll definitely want to come up to a more recent RT as there are a fair number of performance improvements in addition to memory efficiency improvements.

Re: [rt-users] RT : Apache Resource Usage
Hi Jerad Can you can tell me how is your apache configuration that keeps your apache running smoothly and also giving good thoughput to user end as well (i.e loading pages and searches quickly on concurrent request from users). Or provide me with your apache configuration file and configuration of RT Any help is highly appreciated Thanks Varun -Original Message- From: Jerrad Pierce [mailto:jpie...@cambridgeenergyalliance.org] Sent: Thursday, October 22, 2009 8:02 PM To: Varun Cc: rt-users@lists.bestpractical.com Subject: Re: [rt-users] RT : Apache Resource Usage > performance will degrade on concurrent request of RT users.

I have RHEL 4 and its kernel version mod_perl with max time to live set for Apache?

[rt-users] RT : Apache Resource Usage
Hello All I have RT 3.6.3 with fast cgi implemented and apache 2.0 with 8GB of physical RAM. My problem is that after every 3 days my physical ram gets fully utilized and apache starts using swap memory. So my machine gets on its knees. I have no other application running on my machine where I have apache installed and no other process is using memory when I see in top command its just my 30 fastcgi processes takes significant amount of RAM i.e nearly 98% and I cant cut this 30 process to low level as by doing this, performance will degrade on concurrent request of RT users. Can any one suggest me how I can get best of both the worlds i.e giving good performance plus limiting memory consumption also. I have RHEL 4 and its kernel version is 2.6.9-42 Any help is highly appreciable Thanks & Regards Varun Vyas ___ http://lists.bestpractical.com/cgi-bin/mailman/listinfo/rt-users Community help: http://wiki.bestpractical.com Commercial support: sa...@bestpractical.com Discover RT's hidden secrets with RT Essentials from O'Reilly Media.
