Crash on startup with Couchbase Server 2.1.1


#1

Hi,

In a Couchbase 2.1.1 (community edition) deployment, the beam.smp process cores periodically on startup. The backtrace from the core file is:

(gdb) bt

The backtrace looks like the backtrace mentioned in MB-7562 (https://issues.couchbase.com/browse/MB-7562) which mentions that this issue has been fixed in version 2.0.1. So, my questions are:

  • What is the cause of the issue?
  • Has this been fixed in the 2.1.1 Community Edition version?
  • Is it fixed in a later community edition version?

Thanks

Not sure what fix are on which branch for the community edition, maybe @cihangirb can help you.
