    Description

      Hi,

      we have a monitoring, which checks show global status, and one other, which calls SHOW STATUS LIKE 'wsrep_local_state.

      2 nodes works properly, but 3. hangs on*show global status*. After few minutes, it contained hundreds of hang queries and "Too many connections..." error.

      I attached ZIP file with complete PROCESSLIST and all variables.

      Thank you for your check.
