We generate a circular reference exception in translog in 6.8 in the following scenario: - The first rollGeneration hits "too many open files" exception when it's copying a checkpoint file. We will set the tragic exception and close the translog - The second rollGeneration hits AlreadyClosedException as the current writer is closed. We will suppress the ACE to the current tragic exception. Unfortunately, this leads to a circular reference as ACE already suppresses the tragic exception. Other factors that help to manifest this bug: - We do not fail the engine on AlreadyClosedException in flush - We do not check for ensureOpen before rolling a new generation Closes #55893 |
