Odd. I just tried that scenario (crontab(1)-executed "ldmadmin check" with a 
crashed LDM) and it worked fine.

What's the LDM user's login shell? csh(1)? bash(1)? If it's not bash(1), then 
the LDM user's environment might not be correctly set by the bash(1) profile 
files. If it's csh(1), then try this replacement for the crontab(1) entry:

    echo 'bin/ldmadmin check' | csh -l >/check 2>&1 || mail -s '"ldmadmin 
check" problem' address@hidden address@hidden <check.log

It's been a long time since I've done any csh(1) scripting, so you might have 
to experiment with this entry.
