Exception: could not create native thread

mwelss Sep 7, 2007 9:38 AM

After several days (7-11) we get the following exception.
At the time of the exception there about 1000 threads, but
exactly this jboss had more threads earlier in its lifetime.
The server is running Linux, jdk 1.6.0_02, jboss 4.2.1 and jboss-messaging 1.4.2.CR1.

Best regards,

Martin

first get rid of JDK1.6, it's not supported yet.
Messaging got nothing to do with the error you've got, it's screaming about an OOME :) to

get rid of the this exception, limit your stack size to 128k, you can use -Xss128k to specify the stack size.
