simple things first...
if qmail-smptd stops working then the problem is either with qmail-smtpd
or qmail-queue. qmail-queue writes the message in the queue and tells
qmail-send that there is something new to look for. it doesn't complain
when it cannot do this.
I am seing the same problem under redhat linux kernel2.0.35,
supervise+tcpserver, kernel2.0.35. this seems to me that there is some
sort of resource not being freed by kernel when one of tcpserver's
processes die, and perhaps its children have run out of (say)
filedescriptors
next time it happens I'll try stracing tcpserver and seeing what happens.
