attempt recovery on service CRITICAL with nrpe

[donavan nelson]

I'll try this again and include the list :)

I would really clean up the following a bit.  

ERS=`ps -eaf | grep ersjsf | wc -l`

This removes the ambiguity of counting the grep process

ERS=`ps -ef | grep ersjsf | grep -v  "grep" -c`

Because the way your script is written, the first grep could return 0 and you
would fall out and exit with 0.
