      Maxscale configuration:

      [maxscale]
      threads=2

      #we have to move the pid file for pcs
      piddir=/tmp/

      [Galera Monitor]
      type=monitor
      module=galeramon
      servers=server1,server2
      user=maxscale
      passwd=

      {hash}
      monitor_interval=10000
      disable_master_failback=1

      [RWSplitRouter]
      type=service
      router=readwritesplit
      servers=server1,server2
      user=maxscale
      passwd={hash}

      max_slave_connections=100%

      [RWSplitListener1]
      type=listener
      service=RWSplitRouter
      protocol=MySQLClient
      port=3306
      address=x.x.x.x

      [RWSplitListener2]
      type=listener
      service=RWSplitRouter
      protocol=MySQLClient
      port=3306
      address=x.x.x.x

      [server1]
      type=server
      address=x.x.x.x
      port=3307
      protocol=MySQLBackend

      [server2]
      type=server
      address=x.x.x.x
      port=3307
      protocol=MySQLBackend

      Two different applications connection to both listening IP and maxscale stops suddenly. I could not find anything relevant in the trace or debug log.
