in reply to Details of filehandles

Are you using POE::Wheel::Run or something else to set up the IO? P::W::Run has specific methods for catching stdout and stderr.

As usual, it'll probably help if you can post some code that demonstrates the problem.

Edit: the unix program lsof will list open filehandles for all processes, which may be useful.

    I use P::W:R but then this calls subclasses that spawn interactive telnet sessions with remote devices.

    Im trying to identify at the point i try i send a message back where STDERR and STDOUT are pointed to as i think one of the subclasses has it.

    i'll see what i can come up with via lsof
