JVM problems on Hpux 11 L class

[Neil McGrath_1]

Hi,

I'm having a problem with a Java application on an L2000-44. This application runs fine with a 1024 sized heap on solaris, but fails to start when i try to start it with more than 600meg XMS on the HP. So far we've run the java tuning tool and applied the neccesary patches and kernel tweaks but still no success. The box has 2gig of ram and 4 gig of swap, and the system shows that java process has 60meg of memory acquired (once it starts ok), but it wont start with an XMS setting of more than 600meg ?

Possible causes:
- not enough swap space left, or
- kernel parameter MAXDSIZ is very small.

currently MAXDSIZ is 2063835136
swap is untouched at
