HELP!!! cron bugs

[Ed Carp]

Howdy, gang!!  I'm having multiple problems with cron that are making me
tear my hair out:

(1)	cron will sometimes not run jobs scheduled.  It's like cron starts up,
	then ignores anything that's in crontab.  If cron is killed and
	restarted, it runs OK.

(2)	some shell scripts just plain won't run from cron, even though
	they will run from the console or from a remote terminal.  I've checked
	for the obvious stuff, like screen stuff or reads from /dev/tty, stuff
	like that.

(3)	sometimes jobs will just hang cron.  It's like cron does a fork and an
	exec, then waits for the child to finish before it does anything else.

I'm about to toss cron out the window and use vixie-cron, or a homemade
version, but that would not make my boss too happy, since he paid lots of $$$
for the system, and he (not unreasonably) expects the thing to run.  Me?
Hey, I'm a hacker by trade -- I'd replace the damned kernel if I had another
to replace it with! :)

Any help or suggestions would be appreciated.  Oh, I'm running Ultrix 4.0
RISC (Decstation 5000).

Email would be appreciated!
