Per my original post, the conversation actually stops between PHP and imap while things spin -- forever, even on a new TCP connection. I still don't understand why that would block me from hitting login.php again, and getting a new login prompt, that still feels broken. >> >> I also would say that if this plugin is such Bad News, then perhaps it shouldn't ship with base. > > The Filters plugin doesn't have issues just hanging without > explanation.

As stated, conversations between the imapd and php just stopped. I'm happy to let correlation imply causation and say "I had a big problem, it stopped when I turned this off". Given, this may be like saying "I only hear my brakes squeal when I turn off the radio", but in this case, the squeaky thing is the users, and they're no longer complaining. >> People use the SM filters because it's the interface that's available >> to them -- I also have usermin on this system, and suspect I'm going to >> want to hack up the "filters" plugin to basically add a pointer to >> usermin's procmail module, or see if I can get one of the ones that >> actually handles your procmail rules for you working. > > Did you even read the link I pointed you to? Yes, and it was what caused me to try turning off filters to try and alleviate this. My main reason for posting was to get the symptoms documented in case anyone else hits a similar problem. -Dan -- --------Dan Mahoney-------- Techie, Sysadmin, WebGeek Gushi on efnet/undernet IRC ICQ: 13735144 AIM: LarpGM Site: http://www.gushi.org --------------------------- ------------------------------------------------------------------------------ Get 100% visibility into Java/.NET code with AppDynamics Lite!
