The mysqld process crashes after only a few queries. From this error, it's impossible to see what went wrong. Could be a bug, could be an error on our end, but there's no way to tell.

Setup:

All on virtual machines 2 CPU / 2 GB (node3, 4 & 5)
All InnoDB

Crash happens also when running only 1 node
Percona Xtradb cluster Version 5.5.28
*no* messages of any importance before first message in trace below
Information about "no such a transition COMMITTING -> REPLICATING" nowhere to be found (manual, forum, documentation, google) but that could also be a lack of searching skills on my end.

This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
We will try our best to scrape up some info that will hopefully help
diagnose the problem, but since we have already crashed,
something is definitely wrong and this may fail.
Please help us make Percona Server better by reporting any
bugs at http://bugs.percona.com/

key_buffer_size=33554432
read_buffer_size=131072
max_used_connections=7
max_threads=200
thread_count=6
connection_count=6
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 470497 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.
