I also tried :
JAVA_OPTS="-Xmx256m -XX:MaxPermSize=128m"
JAVA_OPTS="-Xmx512m -XX:MaxPermSize=256m"

but still no luck. When I use geronimo with tomcat I got no problems.

Anyone got an idea what to do to solve this problem ?

Strange. I haven't used AIX in a long time. Is there some limit on the number of threads that a java process can start? IIRC you can configure the stack size allocated for each thread ( something like -Xss64k I think...). Reducing the amount of memory that will be allocated for each thread may help...

Alternative is to reduce the number of threads that the AJP Connector will allocate is another option:

In var/config/config.xml


        <gbean name="JettyAJP13Connector">
            <attribute name="host">${ServerHostname}</attribute>
            <attribute name="port">${AJPPort + PortOffset}</attribute>
            <attribute name="redirectPort">${HTTPSPortPrimary + PortOffset}</attribute>

and add 

            <attribute name="maxThreads">1</attribute>
