>Description:
I create login class:
lissyara# grep id100 --after-context=7 /etc/login.conf
id100:\
:coredumpsize=1:\
:cputime=60s:\
:maxproc=12:\
:openfiles=32:\
:priority=20:\
:tc=default:
lissyara#
then, run command:
lissyara# cap_mkdb -v /etc/login.conf
cap_mkdb: 10 capability records
lissyara#
add user:
lissyara# grep ^test1234 /etc/master.passwd
test1234:$1$kj/WOTuN$vLGcOBPv9ro8eljOe.ChA1:1002:1004:id100:0:0:User &:/home/test1234:/bin/sh
lissyara#
add cron job for user:
lissyara# crontab -l -u test1234
* * * * * /bin/sleep 72000
* * * * * /bin/sleep 72000
* * * * * /bin/sleep 72000
* * * * * /bin/sleep 72000
* * * * * /bin/sleep 72000
* * * * * /bin/sleep 72000
* * * * * /bin/sleep 72000
* * * * * /bin/sleep 72000
* * * * * /bin/sleep 72000
* * * * * /bin/sleep 72000
* * * * * /bin/sleep 72000
* * * * * /bin/sleep 72000
* * * * * /bin/sleep 72000
lissyara#
after some time I see lot sleep processes in ps output
lissyara# ps -auxww | grep ^test1234 | grep sleep | wc -l
130
lissyara#
130 > 12
========
If I running commands from ssh session - all OK, I cannot run more than maxproc processes...

It's very serious problem - for shared hostings servers and such other applications where users have access to create cron jobs
