[10/25/2010 -:- 03:28:34 PM] <tarjei> It seems to me to be an error completely
within Camel so I thought I'd report it.
[10/25/2010 -:- 03:30:26 PM] <tarjei> I got the error about 10/30 times having
run about 5m messages through the different routes running in that jvm
[10/25/2010 -:- 03:51:36 PM] <cibsen> and do your prod server have more cpu
cores?
[10/25/2010 -:- 03:51:42 PM] <cibsen> ibm, sun jdk?
[10/25/2010 -:- 03:51:51 PM] <tarjei> Yes - 4. This is openjdk
[10/25/2010 -:- 03:51:54 PM] <tarjei> both places
[10/25/2010 -:- 03:52:03 PM] <cibsen> what os?
[10/25/2010 -:- 03:52:22 PM] <tarjei> Centos 5
[10/25/2010 -:- 03:52:36 PM] <cibsen> yeah kinda figured when you said openjdk
