[Mailman-Users] Error problem

[freebsd]

Hello List,

I have mailman running two lists.   Both are small in user numbers 
running on the same freeBSD 4.3 box with sendmail on Roxen 2.x 
webserver.   Both have been working fine until now.

One of the lists is giveing and error whenever I try to perform and 
administrative function.   Going to the pendign admin tasks page is 
fine but when I either defer, reject, approve or discard any option 
(which are building up) I get the following:

Process.create_process(): exec() failed. errno:7 File not found? Pike

I am unable to figure it out and the other list is functioning 
perfectly.

Any advice kindly appreciated
