[Wrapper-user] conflict between wrapper and libjmp

[Jeff G. <jg...@we...>]

We are running JBoss under control of the wrapper on Linux with java 
1.5, where it works fine. 

When we try to add a jvm profiling option in wrapper.conf of the form

wrapperjava.additional.7=-Xrunjmp:noods,nomonitors,dumpdir=/home/xxx/profiling-results,dumptimer=1000

the java process starts using many times more memory than before during 
the application startup and becomes swap-bound.  The jvm is trying to 
use 2-3x the memory specified in the -Xmx property.  We have not yet 
determined where that memory use is occurring, but wonder if anyone has 
seen issues combining the wrapper native library with libjmp.
