Intermittent .NET / COM / Powerbuilder / EAServer external function issue

Intermittent .NET / COM / Powerbuilder / EAServer external function issue

Intermittent .NET / COM / Powerbuilder / EAServer external function issue

(OP)
Have made a .NET assembly COM Visible to use in Powerbuilder Classic 12.5 deployed to EAServer. The library is registered on the deploy computer (running Windows Server 2003). The problem I am running into is Powerbuilder sometimes cannot find certain functions in the library. Only sometimes and only certain functions (seemingly).

The library in question is for SFTP functionality. One of the problem functions is Disconnect() (there's only one version, no parameters). I can watch the program execute it fine for three connections and then fail to find it on the fourth.

Any suggestions on a cause or solution to this? Is it latency related? Pathing issue? The fact that I'm using four different pieces of technology?
