I am deploying a trigger from a sandbox to a production org. During validation it gives me "maximum trigger depth exceeded" error for some other trigger which is not part of the change set. The error points out to a line number containing insert and says CANNOT_INSERT_UPDATE_ACTIVATE_ENTITY.
When I run individual tests for that trigger in sandbox and production, they pass out with flying colors. I do not see any workflow or field update in production related to that trigger custom object which may cause this.
I dont know where I should start looking. Am I missing something here?
