ZOWE INITIAL STARTUP SPAWNS 1000's of TASKS

Install ZOWE server on ZOS for the first time.
Run thru all the install, config, verify, etc.
When I start the ZOWE server it spawns tasks until it hits MAXPROCSYS.
I have upped MAXPROCSYS up to 4900 and it still hits the MAX.
See these message in STDERR:
/624RSA/usr/lpp/zowe/bin/internal/run-zowe.sh 14: FSUM7726 cannot fork: reason code = 0b250012: EDC5112I Resource temporarily unavailable.
.: /624RSA/usr/lpp/zowe/bin/internal/run-zowe.sh 21: /bin/internal/read-essential-vars.sh: not found

What am I doing wrong?
