Bad File Descriptor (with ClamAV+FreeBSD+Exim+Exiscan)

Hi there,

I'm currently running (successfully) a combination of ClamAV and Exiscan
on FreeBSD.  I get a problem however when I up the concurrency.
Currently I have it set in exim to 30 (so basically this means that
there will be 30 instances of clamc hitting clamd at any one time.  If I
ever bump that up past 30 I get the following:

2004-07-26 11:35:44 1Bp2pU-000GEr-Jv malware acl condition: clamd:
connection to 127.0.0.1, port 3310 failed (Bad file descriptor)
2004-07-26 11:35:44 1Bp2pW-000Fm8-AF malware acl condition: clamd:
connection to 127.0.0.1, port 3310 failed (Bad file descriptor)
2004-07-26 11:35:44 1Bp2pX-000GFR-4l malware acl condition: clamd:
connection to 127.0.0.1, port 3310 failed (Bad file descriptor)
2004-07-26 11:35:45 1Bp2pZ-000GG2-Br malware acl condition: clamd:
connection to 127.0.0.1, port 3310 failed (Bad file descriptor)
2004-07-26 11:35:45 1Bp2pX-000GFW-WB malware acl condition: clamd:
connection to 127.0.0.1, port 3310 failed (Bad file descriptor)
2004-07-26 11:35:45 1Bp2pY-000GAA-7L malware acl condition: clamd:
connection to 127.0.0.1, port 3310 failed (Bad file descriptor)

I've tried increasing all the limits in the clamd.conf file (connection
queue, number of concurrent daemons running, etc).  I've also checked
things like max files open for the OS and its way under the limit.  Do
you think the fault lies with clam, exim, exiscan, freebsd, or a
combination of the lot?

Any help appreciated...

Cheers
Mike
