I added a lot of code to the write method in the project.task model. I need to figure out what's causing the error and for that I need to understand the error. Can someone tell me what this error means or when it's normally raiser.
The whole error message:

TransactionRollbackError: could not serialize access due to concurrent update
I had a constrain on stage_id to send email. The method that send the custom mail causes the error.
