morningman opened a new issue #5679: URL: https://github.com/apache/incubator-doris/issues/5679
**Describe the bug** An error is reported in the Master FE log: `the report queue size exceeds the limit: 100. current: 101` This error will cause all report task from BE to FE fail, resulting in a variety of exceptions in the cluster, such as a large number of transactions in the COMMITTED state that cannot be completed, resulting in data loading blocked. **To Reproduce** One possible reason is that the regularly cleans up thread of expired transactions in FE may clean up a large number of expired transactions during a certain check, and write an editlog when cleaning up each transaction. This is an IO operation. The entire processing flow hold the TransactionMgr write lock, which causes other operations blocked. -- This is an automated message from the Apache Git Service.
