As usual Casper had the answer.

Works for me. I did some checking and the size of a /proc directory
in Solaris 2.6 and Solaris 7, (I didn't check any other versions),
is 16 * v.v_proc. v.v_proc being the maximum number of processes.
Use /etc/sysdef to view your system paramters. Thus my 262336 byte
virtual directory is capable of holding the information for 16394
processes. Tuning that value would alter the size of the /proc
directory accordingly.
