-----------------------------
Summary: 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 (Incubating)
Issue Type: Bug
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.
