Is this the behavior that supposedly indicates a problem with a particular action? Mongrel in development mode randomly hangs on random actions. Further requests cause USR1 logs like: Mon Sep 18 13:04:03 PDT 2006: 0 threads sync_waiting for /, 2 still active in mongrel. Mon Sep 18 13:07:52 PDT 2006: 1 threads sync_waiting for /public/stylesheets/table.css, 3 still active in mongrel. Mon Sep 18 13:08:21 PDT 2006: 2 threads sync_waiting for /, 4 still active in mongrel. 0 threads sync_waiting? Isn''t that good? Sync wait...

Hi One of the two mongrel processes has died in the middle of the night four times in the past 9 days, and I need help debugging this. Each time the symptoms are the same: * Each time I can restart the process via cap -a restart_app. * Before the restart, there is nothing unusual in production.log or mongrel.log. * During the restart, about 100 repetitions of an error message are generated in

Hey folks, I ran into a few people at RubyConf who were having 99% CPU issues. Please contact me if you meet the following criteria: 1. You are running a production site. 2.

....shift t.wakeup if t rescue ThreadError retry end Thread.critical = false begin t.run if t rescue ThreadError end self With Mutex, the next thread to unlock is shifted off the beginning of the array. With Sync, there is one key difference: wait = sync_waiting self.sync_waiting = [] Thread.critical = false for w in wait w.run end With Sync, a copy is made of the array or waiting threads, the waiting thread queue is set to a fresh, empty array, and all of the threads pointed to in the copy are woken up. One will get the lock, an...

Hi list, I''m seeing a couple of issues with Mongrel. I''m running FreeBSD 6.1 and have previously been told that there are known conflicts between this and Mongrel, yet I hope these issues will be resolved with time. I''m overloading Mongrel with httperf on my local workstation. Mongrel is started directly with the mongrel_rails command and there is only one mongrel
