pieter, martin
i don't have any!
all i recall is someone mentioning some time back
(could easily be 12-20 months ago) that they routinely restarted their 0mq
app because of fragmentation issues.
the other was a casual claim that with PUB/SUB, a publisher with no
subs could experience a memory leak.
but listen, these are both old claims and may easily have been
overtaken by events. and i don't won't to start any urban legends here.
i routinely check for loss with valgrind and haven't found any.
we do have issues with memory usage creep, but i've
not completely eliminated issues with user code (as oppose dto zmq code).
so lets pretend i never brought this up, and if i come up
with some more definitive evidence, i will raise the issue again.
thanks
andrew
