EPDM vault unable to access file

Hi everyone,

I am editing workflows in administration and performing test on file transition on a sandbox vault.

All of a sudden (despite being fine before) I am receiving an error whenever I try to delete/check in/transition files on a vault. Essentially the error message will pop up and indicating that the item cannot be accessed.

ex.

Error deleting files

Cause: Could not access item in the database.

I checked the log file in administration and it shows:

Error running query in SpDbOdbc

State=37000

Msg=[Microsoft][ODBC SQL Server Driver][SQL Server]Internal error: Server stack limit has been reached. Please look for potentially deep nesting in your query, and try to simplify it.

Any ideas what can be potential issues that causes this? I highly doubt it's actually a server issue since I am pretty much the only one touching the vault for testing and I am only modifying the workflows/tasks cards etc in administration.

Thanks!
