InnoDB: Error: unlock row could not find a 4 mode lock on the record

[kk r]

Hi All,

InnoDB repeatedly prints this message in the error log:

# InnoDB: Error: unlock row could not find a 4 mode lock on the record

Im not sure if the error message is critical or not, but its definitely not
nice to have in the error log.
After some exploration, I found this error is relevant to Bugs*#41756,
#48306, #53674. *

But I couldn't find out, how to resolve this! Kindly help!

Below are some details.

mysql = 5.1.43
Storage engine = innodb;
transaction-isolation = READ-COMMITTED;
binlog_format = mixed;

Thanks,
