Two of three server nodes crashed 24 hours apart on 5.6.19-25.

We have a three node cluster (db01,db02,db03) and the first two crashed, strangely ~24 hours apart. I'm attaching the stack trace from both and the log from db03, which failed to become primary to boot. The stack trace from both has this in common:

This is on CentOS 6.2 with the following RPM's installed:
Percona-XtraDB-Cluster-server-56-5.6.19-25.6.824.el6.x86_64
Percona-XtraDB-Cluster-shared-56-5.6.19-25.6.824.el6.x86_64
Percona-XtraDB-Cluster-galera-2-2.10-1.188.rhel6.x86_64

Any feedback is greatly appreciated. Thanks!
