Subject Segfault in worker when submitting topology
Date Fri, 03 Jan 2014 18:56:21 GMT

I'm having trouble getting storm set up and submitting a topology. I've 
tried two different installs of storm and associated dependencies:  One 
using the older storm (0.8.1), zeromq (2.1.7) and jzmq (frozen for 
storm).  And then another using the newest of each: storm(, 
zeromq (4.0.3), and latest jzmq master.

Then I'm using the storm-starter package with the WordCountTopology

Storm *appears* to be running fine.  I have one nimbus node and 3 
supervisors.  And the UI looks good.

The topology submits fine:
[storm@thor4 bin]$ ./storm jar 
storm.starter.WordCountTopology wc5
Running: java -client -Dstorm.options= 
-Dstorm.conf.file= -cp 

storm.starter.WordCountTopology wc5
375  [main] INFO  backtype.storm.StormSubmitter - Jar not uploaded to 
master yet. Submitting jar...
389  [main] INFO  backtype.storm.StormSubmitter - Uploading topology jar 
/home/storm/storm-starter/target/storm-starter-0.0.1-SNAPSHOT.jar to 
assigned location:

411  [main] INFO  backtype.storm.StormSubmitter - Submitting topology 
wc5 in distributed mode with conf 
846  [main] INFO  backtype.storm.StormSubmitter - Finished submitting 
topology: wc5

However, it's segfaulting.  I see many hs_err_pid files with the 
following content:
# Problematic frame:
# C  []  zmq::signaler_t::signaler_t()+0x30


Stack: [0x00007f945ac1c000,0x00007f945ad1d000], sp=0x00007f945ad1aed8,

I've spent a few hours troubleshooting but just can't find a solution.  
Can any one make suggestions on what might be wrong?
