Just recentally we have started to get dump files with the following description:

Description: Too many parallel nested transactions

When this happens and the dump files start to get created the server starts begins to time out making the applications crash.

Does anyone have any suggestions on how/what i can do to try and track down this error so i can see what caused it and keep it from happening in the future.

seems like opening and closing of transactions is not properly done from application may be inside loops etc

Run the following command to see which processes have open transactions
SELECT * FROM sys.sysprocesses WHERE open_tran > 0
Once you identify those processes, run this command to see details about those processes
EXEC sp_who2
That will show you various details such as the hostname, program that is invoking running on that spid, what command it is executing etc.
