Do anyone know if there are some hidden limit of 4096 cpus in maui?

Testing shows that a 4096 cpu job will start but not a 4097 cpu job.  I found 
this in the maui log:

12/05 21:37:59 
MQueueSelectJobs(SrcQ,DstQ,HARD,5120,4096,2140000000,EVERY,FReason,FALSE)

Do any one know how to increase this limit?
