Summary : FLUSH TABLES WITH READ LOCK hangs in NULL state There was an issue with a backup script with hanging FLUSH TABLES WITH READ LOCK; due to long running queries. After a fix, the backup script waits for all the processes to finish or it kills the long running queries and after executing the FLUSH TABLES WITH READ LOCK command, its listed with NULL state at the processlist: There are some lines at MysqlOnlineBackup_20140702.log where the NULL state can be seen: Could that be a bug, if yes is it fixable, or what would be the possible workaround ? |

The original request was revoked since the issue is not reproducible anymore on the reporter's side. I suppose we can close it as well. |
