Webmaster Forum / ColdFusion / Server Administration / August 2007

Coldfusion 7,0,2,142559 on Linux, Java VM 1.4.2_09-b05, Apache 2.0.52

CF hangs every few days. It happens with all pages (so with or without db
access).
HTML keeps working fine. The CF logs show no errors.

I did a thread dump of the server in hanging state. There are no jrpp- or web-
threads at all. Is that a problem?

Full thread dump Java HotSpot(TM) Server VM (1.4.2_09-b05 mixed mode):
