Deadlock issues

Posted on by ErikKornerup 200

Occasionally I get a deadlock error when creating customers using the custCustomerV3Entity.

It is caught by the try catch block structure so data is fine.

However I can't see which table has caused the deadlock.

It can be contactinfo or any other table used in the entity which is blocked for update by another process.

I can't see which method in the update process that has caused the deadlock as the xsession::xppcallstack only shows the call stack until the method where the try catch block is placed.

Therefore - is there any way I either can see the tables that caused the deadlock or the call stack, so I can investigate which tables cause the deadlock

    Hi ErikKornerup,

    Do you import customer in Excel format manually via Customers V3 entity?

    Hi

    No I insert into a staging table and this staging table is used in a batchjob to create customer table records using the customersV3 entity

    Hi Erik,

    Can you try to import the data via Excel file in Data Management to check if you get the error message while import?

    It would be great to use the same heading and values that you use via insert.

    In a Production environment, if you open LCS in environment monitoring you list all events of type "All deadlocks in the system" and try to get the source of error.

    In Sandbox or dev environments you can use SQL Server to detect deadlocks

    I know that, but i would like to add the information of the locked tables in the infolog, so it is clear  for the end user which table has the deadlock.

    The error comes from time to time and therefore it is not an option to use Excel. The error occurs because another process is updating the table, but as I can't see which table is deadlocked, I can't investigate which process is the sinner :-)

    In code, I'm not aware. Only using LCS to track the source of the error.
