InnoDB: Assertion failure

Hi there.

We are running a three-node pxc. During a performance test, one node is permanatly (after a few minutes; up to 1,5 h) crashing with the following error:

Is this a bug or just a false configuration parameter for the percona cluster? I am kind of clueless how to fix this issue. I read about downgrading the system from
5.6 (5.6.15-56 is the version we are using) to 5.5.XX

Thanks for any help in advance

We ran into a bug which is fixed in the latest release of Percona/Galera. Thread can be closed.
