. The current transaction is not rolled back. . I had forgotten to close a debug console that I had left in the middle of a transaction. So i don't writing proper mysql query is a factor here.
The big problem with this exception is that its usually not reproducible in a test environment and we are not around to run innodb engine status when it happens on prod. All inserts are of this form, so no bulk inserts nor mix mode inserts etc. Since my database is on a web server, I couldn't restart the database. So i found out that the key of the primary key was 11 and the foreign keys 10. I have configured to retry 4 times. I am not able to point out this problem.
Several other modules were throwing the error in my logs as well, my dev and staging sites are on two different servers and it was only happening on one, so I knew it had to be a server configuration issue. In my instance, I was running an abnormal query to fix data. . How can I fix this table and remove the stuck transaction from it? By setting this I think your problem will be get solved.

I don't even think this is a bug, it's perfectly valid for Commerce to lock the order row when an order is loaded but doesn't provide a way for an order to be loaded without locking the order row for times when the caller isn't going to make changes to the order. Problem goes away completely if I stop Commerce's pessimistic locking. . However It is possible a different issue is the cause of this. Is it only the dead locks area that is interesting for this issue? I have no idea what could be causing these locks. .
