This bug is not fixed. A PXC with 5.6.29 crashed after filling up the disk space with gcache files:

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.

Hope that's ok; if not, decrease some variables in the equation.
