I have a two node Galera cluster on dedicated servers directly connected by Ethernet cable.
For last three days, on one nodes Galera creates GRA_-.log files of 1GB approximately every 1,5-2 hours. These files would fill up empty space on drive within 2 days.
When analysing GRA log, I get nothing of sense. File start with this lines:
^[[H^[[J/*!50530 SET @@SESSION.PSEUDO_SLAVE_MODE=1*/;
/*!40019 SET @@session.max_insert_delayed_threads=0*/;
/*!50003 SET @OLD_COMPLETION_TYPE=@@COMPLETION_TYPE,COMPLETION_TYPE=0*/;
DELIMITER /*!*/;

I tried yesterday to restart mysql on this node - it didn't help.
Today I performed SST transfer from other node - it didn't help.
