i realise its crass to ask for help in a complicated program, but i'd
appreciate any hints on what to look at.
i am running version 2.0.9 on a red hat enterprise 5.4 system
(actually several nodes identically setup).
the program (digest) has a main thread which opens several sockets
successfully.
it passes the zmq context to a few other threads, who then open one
or two zmq sockets to work on.
the problem is this: digest fails to work on exactly one system
(nisus01) in the following way:
any call to zmq_socket in a thread other than the main thread fails
with no useful errno.
(the types include ZMQ_SUB and ZMQ_PUSH.) the same binary and same
libraries
work on other nodes just fine. similiar programs using zmq run just
fine on nisus01.
i've asked my sysadmin to reboot nisus01 to see if that changes
anything.
is there anything else to look at? i've run everything with valgrind
to make sure
i'm not stomping on memory. is there some non-thread safe weakness
with zmq_socket?
