There's no incompatibility that I'm aware of; this mailing list is hosted by
mailman and filtered by spamdyke with no problems.
A few questions: Is the mailman process running on the same server as spamdyke,
or a different one? What OS and version are you running? What versions of
spamdyke and mailman?
Since you seem to be able to trigger this bug relatively easily, it would be
extremely helpful if you could recompile spamdyke with excessive output (run
"./configure --with-excessive-output ; make"), then enable full logging
("full-log-dir" option). The log from one of these "stuck" processes should
show exactly what spamdyke is doing when the bug occurs and would probably
contain all the info I'd need to reproduce it and fix it. It'll contain real
domain names and such, so you'll probably want to send it to me privately.
As soon as I can figure out how to trigger this myself, I should be able to fix
it very quickly.
