Description

If a partition in the write-ahead-log throws an IOException while in the rollover() method (called from the checkpoint method of MInimalLockingWriteAheadLog), the partition is not blacklisted. As a result, it can still be written to, and this can cause corruption if it is then written to again before being rolled over.
