Fixed Bugs

  • PXC-2281: Debug symbols were missing in Debian dbg packages.
  • PXC-2220: Starting two instances of Percona XtraDB Cluster on the same node could cause writing transactions to a page store instead of a galera.cache ring buffer, resulting in huge memory consumption because of retaining already applied write-sets.
  • PXC-2230rgcs.fc_limit=0 not allowed as dynamic setting to avoid generating flow control on every message was still possible in my.cnf due to the inconsistent check.
  • PXC-2238: setting read_only=1 caused race condition.
