For the past few days, we've been getting the following error.
Error while log archival and clean-up for table "AU_TRANSACTIONLOG"
Lock wait timeout exceeded; try restarting transaction
This is on the cluster environment with one shared database.
This error usually comes when the table is locked out in case of large data present in it or due to the large number of uncommitted transactions etc. If you'll try to delete a bunch of records using MYSQL administrator or some other DB tool then you'll receive the same error.
Increasing value of innodb_lock_wait_timeout should resolve your issue. We would recommend to consult your DBA for an expert advice to remove the lock on the table "AU_TRANSACTIONLOG". Also Refer the below link for more information:.
