WSREP: Writeset deserialization failed: Unsupported RecordSet version: 2: 71 (Protocol error)

We are running a Mariadb galera cluster with 3 data nodes. Recently one of them crashed and I had to do a SST (State Snapshot Transfer). Nothing I haven't done or seen before. However, after the SST was completed the process crashed on the following WSREP error: [ERROR] WSREP: Writeset deserialization failed: Unsupported RecordSet version: 2: 71 (Protocol error) at galerautils/src/gu_rset.cpp:header_version():272 at galera/src/trx_handle.cpp:unserialize():268 complete logs: mysqld: 2018-10-24 15:03:41 139769088514304 [Note] InnoDB: 128 rollback segment(s) are active. mysqld: 2018-10-24 15:03:41 139769088514304 [Note] InnoDB: Waiting for purge to start mysqld: 2018-10-24 15:03:41 139769088514304 [Note] InnoDB: Percona XtraDB (http://www.percona.com) 5.6.39-83.1 started; log sequence number 335729536918 mysqld: 2018-10-24 15:03:41 139764732757760 [Note] InnoDB: Dumping buffer pool(s) not yet started mysqld: 2018-10-24 15:03:41 139769088514304 [Note] Plugin 'FEEDBACK' is disabled. mysqld: 2018-10-24 15:03:41 139769088514304 [Note] Recovering after a crash using /var/log/mysql/mariadb-bin mysqld: 2018-10-24 15:03:41 139769088514304 [Note] Starting crash recovery... mysqld: 2018-10-24 15:03:41 139769088514304 [Note] Crash recovery finished. mysqld: 2018-10-24 15:03:41 139769088514304 [Note] Server socket created on IP: '0.0.0.0'. mysqld: 2018-10-24 15:03:42 139769088514304 [Note] WSREP: Signalling provider to continue. mysqld: 2018-10-24 15:03:42 139769088514304 [Note] WSREP: SST received: 1b859078-cacc-11e8-8e3e-4381b13e7545:4661474 mysqld: 2018-10-24 15:03:42 139769088514304 [Note] Reading of all Master_info entries succeded mysqld: 2018-10-24 15:03:42 139769088514304 [Note] Added new Master_info '' to hash table mysqld: 2018-10-24 15:03:42 139769088514304 [Note] /usr/sbin/mysqld: ready for connections. mysqld: Version: '10.1.36-MariaDB-1~xenial' socket: '/var/run/mysqld/mysqld.sock' port: 3306 mariadb.org binary distribution mysqld: 2018-10-24 15:03:42 139769088199424 [ERROR] WSREP: Writeset deserialization failed: Unsupported RecordSet version: 2: 71 (Protocol error) mysqld: at galerautils/src/gu_rset.cpp:header_version():272 mysqld: at galera/src/trx_handle.cpp:unserialize():268 mysqld: WS flags: 0 mysqld: Trx proto: 3 mysqld: Trx source: 00000000-0000-0000-0000-000000000000 mysqld: Trx conn_id: 18446744073709551615 mysqld: Trx trx_id: 18446744073709551615 mysqld: Trx last_seen: -1 mysqld: 2018-10-24 15:03:42 139769088199424 [ERROR] WSREP: Unsupported RecordSet version: 2: 71 (Protocol error) mysqld: at galerautils/src/gu_rset.cpp:header_version():272 mysqld: at galera/src/trx_handle.cpp:unserialize():268 mysqld: 2018-10-24 15:03:42 139769088199424 [Note] WSREP: applier thread exiting (code:7) mysqld: 2018-10-24 15:03:42 139769088199424 [ERROR] WSREP: node consistency compromised, aborting mysqld: 2018-10-24 15:03:42 139769088199424 [Note] WSREP: starting shutdown mysqld: 2018-10-24 15:03:42 139769010707200 [Note] /usr/sbin/mysqld: Normal shutdown mysqld: 2018-10-24 15:03:42 139769010707200 [Note] WSREP: Stop replication mysqld: 2018-10-24 15:03:42 139769010707200 [Note] WSREP: Closing send monitor... mysqld: 2018-10-24 15:03:42 139769010707200 [Note] WSREP: Closed send monitor. mysqld: 2018-10-24 15:03:42 139769010707200 [Note] WSREP: gcomm: terminating thread mysqld: 2018-10-24 15:03:42 139769010707200 [Note] WSREP: gcomm: joining thread mysqld: 2018-10-24 15:03:42 139769010707200 [Note] WSREP: gcomm: closing backend mysqld: 2018-10-24 15:03:42 139768797067008 [Note] WSREP: 3.0 (dbserver08): State transfer from 2.0 (DB) complete. mysqld: 2018-10-24 15:03:42 139768797067008 [Note] WSREP: Shifting JOINER -> JOINED (TO: 4666631) mysqld: 2018-10-24 15:03:42 139769010707200 [Note] WSREP: view(view_id(NON_PRIM,2b30f5eb,167) memb { mysqld: 7bffa222,0 mysqld: } joined { mysqld: } left { mysqld: } partitioned { mysqld: 2b30f5eb,0 mysqld: 30d0c86b,0 mysqld: 5a7b95e7,0 mysqld: b0f6da74,0 mysqld: f7e81556,0 mysqld: }) mysqld: 2018-10-24 15:03:42 139769010707200 [Note] WSREP: view((empty)) mysqld: 2018-10-24 15:03:42 139769010707200 [Note] WSREP: gcomm: closed mysqld: 2018-10-24 15:03:42 139768797067008 [Note] WSREP: New COMPONENT: primary = no, bootstrap = no, my_idx = 0, memb_num = 1 mysqld: 2018-10-24 15:03:42 139768797067008 [Note] WSREP: Flow-control interval: [16, 16] mysqld: 2018-10-24 15:03:42 139768797067008 [Note] WSREP: Trying to continue unpaused monitor mysqld: 2018-10-24 15:03:42 139768797067008 [Note] WSREP: Received NON-PRIMARY. mysqld: 2018-10-24 15:03:42 139768797067008 [Note] WSREP: Shifting JOINED -> OPEN (TO: 4666631) mysqld: 2018-10-24 15:03:42 139768797067008 [Note] WSREP: Received self-leave message. mysqld: 2018-10-24 15:03:42 139768797067008 [Note] WSREP: Flow-control interval: [0, 0] mysqld: 2018-10-24 15:03:42 139768797067008 [Note] WSREP: Trying to continue unpaused monitor mysqld: 2018-10-24 15:03:42 139768797067008 [Note] WSREP: Received SELF-LEAVE.

What does this WSREP error means? I tried googling this specific error message but nothing came up. I also checked mariadb versions differences between the nodes as I recently had to reinstall a node. But I couldn't spot any difference between them.
