DbConnection Pool Error (Microsoft.Win32.SafeNativeMethods.ReleaseSemaphore)

I am getting this error in my VB.NET code. Anyone have ideas on what it could be or how to troubleshoot. I am using SQL Server 2008 and this error doesn't happen consistently. Looks like it happens completely randomly and doesn't seem to be originating from my code:

MESSAGE: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

Seems like it's an issue with the object being disposed of or the reference has changed (memory pointer that is). Can you post any code?

I read a blog once that the person had experienced a similar problem. They had upgraded from 32 to 64 bit and had not changed their build properties target platform. You might start there.
