The problem lies in the fact that there is a SYSGEN parameter set in 
the CURRENT parameters in VAXVMSSYS.PAR that is too low. When the system 
boots, SYSBOOT sets the ACTIVE parameter to the minimum value needed but 
does not update the CURRENT parameter. To determine which parameter is set 
wrong try the following...

$ RUN SYS$SYSTEM:SYSGEN
SYSGEN> USE CURRENT
SYSGEN> SET/OUTPUT=CURRENT.TXT
SYSGEN> SHOW/ALL
SYSGEN> USE ACTIVE
SYSGEN> SET/OUTPUT=ACTIVE.TXT
SYSGEN> SHOW/ALL
SYSGEN> EXIT

Then just run the difference utility on the two files. The bad parameter
will then show up.

This general approach also works for the two common messages:

%SYSBOOT-W-Maximum WS raised to PHD+MINWSCNT
If this is displayed then WSMAX is too small.

%SYSBOOT-W-WS default and quota raised to PHD+MINWSCNT 
In which case PQL_DWSDEFAULT is too small.


A common mistake that is made is when one needs to change a SYSGEN parameter
for a new layered product one typically does the following...

$ SET LOGINS/INTERACTIVE=0
$ MCR SYSGEN
SYSGEN> SET parameter_name value
SYSGEN> WRITE CURRENT
SYSGEN> EXIT
$

The mistake here is that when the logins were disabled, the parameter IJOBLIM
in the ACTIVE parameters was set to 0. Then when SYSGEN was invoked, by default 
it used the ACTIVE parameters. After the value was changed, IJOBLIM was written 
out to the CURRENT parameters as 0 (an illegal value for the system at boot). 
Next time the system boots you'll get the "%SYSBOOT-W-VALUE set to minimum"
warning.

The correct thing to do is to issue the command

SYSGEN> USE CURRENT

as soon as you get into SYSGEN or better yet use AUTOGEN.COM to set all the
parameters right.


	hope that helps...
