Rick Kellogg updated STORM-83:
------------------------------
Component/s: storm-core
> zeromq send can cause divide by 0 in multithreaded cod
> ------------------------------------------------------
>
> Key: STORM-83
> URL: https://issues.apache.org/jira/browse/STORM-83
> Project: Apache Storm
> Issue Type: Bug
> Components: storm-core
> Reporter: James Xu
> Priority: Minor
>
> https://github.com/nathanmarz/storm/issues/474
> When running the unit tests I got a SIGFPE (FPE_INTDIV) in
> zmq::lb_t::send(zmq_msg_t*, int)+0x176 I traced this down to line 137 of
> lb.cpp in version 2.1.7 of zeromq. The error is a divide by 0 error. The
> denominator in this code is an active count, and about 7 lines above active
> passed a check for 0. zmq::lb_t is very much not thread safe, but it looks
> like we are somehow calling a single instance of it from multiple threads.
