Has anyone ever seen this error?

Active Server Pages error 'ASP 0115'

Unexpected error

/iisHelp/common/500-100.asp

A trappable error (C0000005) occurred in an external object. The script
cannot continue running. error '80029c84'

Circular dependency between types/modules.

/MIGRAINE/include/DBConnect.asp, line 9

DBConnect.asp is an include I use to create a connection to a DB2 database.
I have been using and developing the code over weeks and then this error
abruptly started. I relize that I have not given any details to the code,
but I was hoping someone has seen this error before. My application is very
large and the first call to the database at sign on creates this error.

Thanks,

Gary
