Hello,
I had a thread in the other CRM forum but had to close it due to one of the questions I had being solved.
I have several plugins that are doing updates and needed to add one more that specifically creates write in products on the quote, migrating them from a custom entity on the opportunity.
Since I did this I started having deadlocks in the database.
I made some traces to the DB and one of them is as shown below:

I set the parallelism on the DB to 1 , turned on read commited snapshot and transaction isolation level to snapshot as well as suggested by several posts I read.
Still to no avail.
Odd thing is sometimes the process(asynchronous) runs well. Yesterday I tried to creat 10 quotes in a row to trigger the whole process and the result was:
Execution 1 and 3 gave a deadlock. All the others ran just fine. It was exactly the same quote creation with the same amount of products.
My question is, where can I go from here? How can I approach this problem?
If someone could help me that would be great.
Thanks for your time.
