I'm still hunting the origin of the "Bad File Descriptor" errors we get at random points in our tools.

I found another lead....I've searched here and Googled, but no love so far. Any time the "Bad File Descriptor" shows up in my application logs, I get an error showing up in the Windows System Event Viewer stating:

"Application popup: perl.exe - Application error: The instruction at "0x77c46fa3" referenced memory at "0x0188d000". The memory could not be "read""

A couple of interesting(?) tidbits:

The first memory location remains static. On every error I've found, it's "0x77c46fa3".

The second memory location is static per machine. On different machines it may be "0x0188d000", or "0x01889000", or "0x0188c000", but it remains constant across errors on a given machine

The second memory location is always something similar to what I describe above: 0x0188{$FOO}000, where $FOO is the only bit changing

I'm way over my head at this point, but I'm hoping this will help someone point me in the right direction.
