Subject: losing connections to FCGI procs

I have been having the following problem for quite a while with my FastCGI
perl scripts under Apache 1.1.1/mod_fcgi 1.4.  Every so often, one or more
of the fcgi apps will become unreachable through its named pipe.  The
following errors will then occur in the error_log every time the script is
accessed (and the user gets a 500 server error).

[Thu Dec  5 10:21:52 1996] access to /home/www/prod/merc/cb/cgi/cb_merc.cgi f

ailed for 205.160.40.26, reason: mod_fastcgi: OS error 'Connection refused'

The problem is completely sporadic.  If I restart the server, the problem
might come back after a minute, or it might not happen again for 8 hours.
Does anyone have a clue what's going on here?  Stanley?
