Either the milter died or the T= values in the INPUT_MAIL_FILTER() might 
need tweeking w.r.t. to you server load:

	T=C:30s;S:10s;R:30s;E:10s

Sounds like T= are too short.

Also are you using the default values for -g and -t options?

Its a bit misleading this particular case. What appears to happen is 
that the connection to aborted and closed before filterOpen() is called 
and so when filterClose() is called, it reports that the workspace is 
missing. I've seen this in some of my other milters and considered 
disabling it in filterClose().

Now this one I've not seen before and looks like sendmail's libmilter 
can't create a new thread. How many connections are you handling per 
minute? Can you adjust the process thread limit higher?
