New processes, quite possibly; I've seen this happen before.
Sendmail ought to have some way of limiting the number of
simultaneous processes; see if you can set it and then try to
force the hang.

You may also have user processes that group without limit.  See
if you can get a systat or other *stat running on a virtual
console when the problem occurs; it might show interesting
results.
