wohali opened a new issue #2437: Hung beam.smp sitting at 100% CPU
URL: https://github.com/apache/couchdb/issues/2437
 
 
   ## Description
   
   ```irc
   13:56 <+davisp> 1) I've seen some test cases sit idle for 40-50m+. SSH'ing 
to the node
                   holding that job shows beam.smp spinning at ~100% CPU on the 
node.
                   Unfortunately using `kill -SIGUSR1 $pid` to try and generate 
a crash dump
                   does not work.
   ```
   
   ## Steps to Reproduce
   
   Unsure so far. Perhaps an EUnit soak test would work.
   
   ## Expected Behaviour
   
   beam should not hang.
   
   ## Your Environment
   
   This has occured on IBM Cloud (x86_64, docker) workers as well as our 
FreeBSD (12.1, iocage, no docker) workers during various builds.
   
   ## Additional Context
   
   Unclear if this is specific to Jenkins, to the version of Erlang we're 
using, or if this is genuinely a release blocking issue.
