IMSP v1.5a6 on FreeBSD Crash

[Ted Fines]

The IMSP daemon will occassionally quit with the following console message:
imsp[934]: imsp exiting: accept (0x4809a8ac): Software caused connection 
abort.

This possibly related cause was found via Google:
"'Software caused connection abort'. The Berkeley definition is something 
like: 'A connection abort was caused internal to your host machine. The 
software caused a connection abort because there is no space on the 
socket's queue and the socket cannot receive further connections."

The imspd is installed with the imsp-ia add-on, which allows it to 
authenticate to the IMAP server, in case that tells you anything.

Any thoughts?

Thanks,
