On a test server configured with threadtimeout set to 120, minthreads not set (defaults to 1/0 I think), and maxthreads set to 40, I have another server reference a URL every 5 seconds. What I see on the test server is:
[17/Oct/2001:19:17:49][9533.8200][-conn0-] Notice: monitor: returning page [17/Oct/2001:19:17:54][9533.8200][-conn0-] Notice: monitor: returning page [17/Oct/2001:19:17:59][9533.8200][-conn0-] Notice: monitor: returning page [17/Oct/2001:19:18:04][9533.8200][-conn0-] Notice: monitor: returning page Then I go click around on the site to cause another thread to launch to handle the demand. Then stop clicking to let things settle down. Now I see this: [17/Oct/2001:19:19:55][9533.8200][-conn0-] Notice: monitor: returning page [17/Oct/2001:19:20:00][9533.14345][-conn1-] Notice: monitor: returning page [17/Oct/2001:19:20:05][9533.8200][-conn0-] Notice: monitor: returning page [17/Oct/2001:19:20:10][9533.14345][-conn1-] Notice: monitor: returning page [17/Oct/2001:19:20:15][9533.8200][-conn0-] Notice: monitor: returning page [17/Oct/2001:19:20:20][9533.14345][-conn1-] Notice: monitor: returning page [17/Oct/2001:19:20:25][9533.8200][-conn0-] Notice: monitor: returning page [17/Oct/2001:19:20:30][9533.14345][-conn1-] Notice: monitor: returning page This shows (I think) that if you currently have N threads active, no threads will timeout if there are N hits in threadtimeout seconds, at least on a Linux box, because the thread scheduling is FIFO instead of LIFO. On one of our production server, we are up to around 26 active threads. I don't think there is any value for threadtimeout that would make threads actually time-out. I dunno if there is a way to make Linux/pthreads/AS/... wakeup threads in LIFO order instead of FIFO. Anyone else know? Jim
