[Info-vax] Process memory settings

[Syltrem]

I have a process running some program and while it does so,
$ write sys$output F$GETJPI("","WSSIZE")
grows until it reaches
$ write sys$output F$GETJPI("","WSAUTHEXT")

Then I get
%LIB-F-INSVIRMEM, insufficient virtual memory


How do I raise the Authorized Working Set Extent ?
I tried WSEXT in Authorize with no luck, also Sysgen's PQL_MWSEXT

This is efinitely not something I play with very often, and I can't seem to 
find anything with Google...

Pls help !
Thanks
