Using 5.6.20-68.0-56-log Percona XtraDB Cluster
I am receiving a similar node crash when a nightly OPTIMIZE_TABLE was running:

2014-10-09 00:33:45 57717 [ERROR] WSREP: Trx 47399098 tries to abort slave trx 47399100. This could be caused by:
1) unsupported configuration options combination, please check documentation.
2) a bug in the code.
3) a database corruption.
Node consistency compromized, need to abort. Restart the node to resync with cluster.
