Re: [rt-users] apache 100% cpu usage
I tried to examine your idea about big search. I did some of them (i.e. 128000 results) but httpd process only peaked (still not 100%) and in a few seconds get back to the normal state. It seems search with large result could not be the exact source if this problem Best Regards From: rt-users-boun...@lists.bestpractical.com [mailto:rt-users-boun...@lists.bestpractical.com] On Behalf Of Payam Poursaied Sent: Sunday, March 20, 2011 8:55 PM To: 'Ruslan Zakirov' Cc: rt-users@lists.bestpractical.com Subject: Re: [rt-users] apache 100% cpu usage Hi Ruslan Thank you for your response.

Look at updates for the module. Try to wait to see if it ends. If it ends then may be It's result of a big search that stored in the session. Newer versions of RT don't store big search results in sessions, only limited amount of records. Check sessions table for big records. Regards, Ruslan.

I tried to compile apache in debug mode and then wait to see a suspicious process and then attached GDB66 to that cpu intensive httpd process to find out what is going on. But I could not go further more. I have also consulted with apache-freebsd mailing list but there wasn't any success. Could anyone help me to drill down this problem?

Re: [rt-users] Some advice on initial config
Okay, that makes sense. So I thought a different approach might be in order. Instead of having ExtertnalAuth create the privileged RT support users I'd have it create and authenticate all users as none unprivileged and manually set the support users to the correct group. The first problem I've encountered is that ExternalAuth doesn't seem to recognise the 'Domain Users' group in AD. It works fine if I explicitly add the user to the 'RT User' users group I set up from the wiki howto doc but not if I either set the 'Domain Users' group in the ExternalAuth RT_SiteConfig.pm or if I add it as a member of the 'RT Users' group. Anybody know why that might be as adding them individually to 'RT User' will be a pain. Thx for any feedback. -np -- Tradar Limited is a limited company registered in England and Wales.

I'm on Debain Squeeze, Apache2 and RT3.8 with MySQL I've got it the web interface up and even managed to get emails to flow from our exchange server into the general queue so I have the basics. My problem is with the users. I've managed to get the ExternalAuth plugin to talk to AD/ldap and create privileged user but I'm having problem setting RT up so that the folks submitting emails/tickets to it can log in and see the queue and theirs/others tickets. An email will arrive and create a ticket and create a user with *NOPASSWORD* but for the life of me I can't seem to be able to login with that user. Even is if users has the 'Let this user acess RT' check set. These are internal unprivileged users that aren't authenticating through ExternalAuth and you've configured external auth to fall through to internal users? If so, they need a password to login.

When using the web interface (i.e. via the 'Basics' or 'Jumbo' tab), the CF doesn't appear intially but after an update is made to any item and saved, the CustomField appear.

I finally was able to upgrade one of the affected instances to 3.8.9 and can confirm that my problem has been fixed.
[rt-users] RT Content-Type default to text/html
Hello, Based on setting the content-type to text/html, looks like RT would send it as multi-part message with both text and HTML as attachments. https://github.com/bestpractical/rt/blob/rt-3.8.7/docs/templates.pod#Special_Headers I was wondering if there is a way to always have the default email as HTML, and does not go out as multi-part email. Basically the email can be viewed directly in Outlook and other email clients supporting HTML rather than asking users to open attachments explicitly. Thanks,

It sends as multipart/alternative so your MUA chooses which one to display. RT doesn't support sending HTML only email. You should provide more specifics about what your templates look like, sample RT email, your RT version, more information about how Outlook mishandles it, etc etc. -kevin [1]https://github.com/bestpractical/rt/blob/rt-3.8.7/docs/templates.pod#Special_Headers I was wondering if there is a way to always have the default email as HTML, and does not go out as multi-part email.
