cronolog followup - extra sh session?

[L. V. Lammert]

Trying to get a cronolog config worked out for one of our servers, .. 
noticing something strange:

 2513 ??  I       0:00.01 /usr/local/sbin/cronolog 
--link=/u/omnitec/logs/error . . .
 9216 ??  I       0:00.04 /bin/sh -c /bin/sh
cronolog is working correctly, .. BUT it also seems to be launcing a sh 
session for each process cronolog (i.e. 8 log files = 8 sh sessions)! Does 
anyone know why it's doing that? Is it normal?

        Thanks!
