Python Crash when running with slaves

[reistiago]

Python crashes, a popup appears with: "python quit unexpectedly while using the libzmq.so plug-in."

On terminal:
Permission denied (bundled/zeromq/src/stream_engine.cpp:785)
Abort trap: 6

Versions

• OS: 10.9.2
• Python: 2.7.5
• Locust 0.7.1
• pyzmq 14.3.0

What version of ZeroMQ do you have? You can check it by typing the following in a python shell:

import zmq
zmq.zmq_version()

[reistiago]

zmq - '4.0.4'

[heyman]

Hm, okay.

I've seen strange issues with python packages and other libs that had been compiled before upgrading to OSX Mavericks (10.9). I would try to re-install the following:

python, libevent, zmq, locust

And see if that fixes it.

[reistiago]

Reinstalled everything, still the same error.

[heyman]

Hmm, okay. Have you tried starting it as root (since the error message said "Permission denied")?

[reistiago]

Tried with root, same result.

Another detail, this doesn't happen when it starts to run, it happens after running successfully for a while.

[heyman]

Okay, does it happen every time? How long before it happens (apporximately). How many slaves are you using. What's the number of requests/second?

Basically, any detail that could potentially help reproducing the issue :).

[reistiago]

I would say every time. Shortly after reseting stats. between 1 to 3
slaves. Always more then 2000 requests / second.

If you need me to do some trials let me know.

Have you checked the maximum number of open files? You might need to increase it. On OSX, I believe you can check it using: launchctl limit
