Not full cleanup at crash

On related note:

When JOINER gets error
"110614 12:54:00 [Warning] WSREP: 1 (localhost.localdomain): State transfer to 0 (localhost.localdomain) failed: -12 (Cannot allocate memory)" from DONOR,

I guess it makes sense to try another DONOR, rather than crash mysqld.

However in this case, there was only one DONOR, so probably it was correct decision.

I still have this problem using revision 3099

Vadim,

You need to update xtrabackup sst script to monitor the state of the parent mysqld process. Check how it is done in wsrep_sst_rsync.sh.
