Question
CF8 crashes java.lang.OutOfMer moryErronable to create new native thread
Over the past few weeks we have not been able to stabilize
one of our web servers running, duel quad processors, 4GB RAM, CF8,
MWS2003 x64, IIS6, and SQL 2005 (installed on another box). About
every 12 hours we encounter ‘08/12 13:55:48 error ROOT CAUSE:
java.lang.OutOfMemoryError: unable to create new native thread’ which causes all the sites in IIS to display ‘Service Unavailable’ ‘There is no web application configured to service your request’.
I have changed JVM heap to 1024m, the perm size to 256m, and the simultaneous request to 24 but to no avail.
It is important to note that we have an identical configuration on other boxes which have much higher traffic and they don’t have an issue. This box have much less traffic overall but more sites.
I turned on metrics Web threads for JVM:
.....
08/12 09:11:38 metrics Web threads (busy/total): {jrpp.busyTh}/{jrpp.totalTh} Sessions: 0 Total Memory=402176 Free=123250
08/12 09:11:43 metrics Web threads (busy/total): {jrpp.busyTh}/{jrpp.totalTh} Sessions: 0 Total Memory=402496 Free=141132

08/12 09:12:18 metrics Web threads (busy/total): {jrpp.busyTh}/{jrpp.totalTh} Sessions: 0 Total Memory=403968 Free=125020

Any help is greatly appreciated.
