Deadlock in mysql

I get this error in the application lock on my server:

Is this an implementation problem og the MySql adaptor or something deeper ? It happens a few time every day but not related to specific events.

MySql.Data.MySqlClient.MySqlException (0x80004005): Deadlock found when trying to get lock; try restarting transaction

I have these details:
executing
INSERT INTO DistributedLock (Resource, CreatedAt) SELECT ‘locks:schedulepoller’, ‘2017-01-15 05:04:35.387605’ FROM dual WHERE NOT EXISTS ( SELECT * FROM DistributedLock WHERE Resource = ‘locks:schedulepoller’ AND CreatedAt > ‘2017-01-15 05:03:35.387605’)

executing
INSERT INTO DistributedLock (Resource, CreatedAt) SELECT ‘expirationmanager’, ‘2017-01-15 05:04:35.387605’ FROM dual WHERE NOT EXISTS ( SELECT * FROM DistributedLock WHERE Resource = ‘expirationmanager’ AND CreatedAt > ‘2017-01-15 05:04:05.387605’)

*** WE ROLL BACK TRANSACTION (2)

I have the same question。 any progress? thanks

Do we know what is the cause of it? How to fix it?
