Description:when we use the asterisk feature:
atxfer => ASTERISK-1                    ; Attended transfer
we experience a hangup when we turn the "smart" transfer, into a "blind" one.
meaning, after a call is made between A and B, and A wants the transfer B to C,
he press the right digits to play the DTMF's for "atxfer", get the ring tone after the "transfer" playback, dial to extension C and press the pound key.
when it starts to ring - the call between A and C (B is on hold) - A hangs up to turn the "smart" transfer into "blind". the moment A hangs up, the call is terminated for all sides.

the only error i found in the full log is -
"file.c: Failed to write frame"

I don't quite understand what you're doing here? Are you saying you're using the attended transfer as a blind transfer?

So A answers a call from B
A hits the DTMF associated with the attended transfer, and then dials C
While C is ringing, A hangs up, and then the call from B and the call to C are dropped?

yup.
if you use attended transfer but you hangup before the third party answers you, the call will be transfered blindly.

but for some reason on one - only one - of our servers, the call drops as aslmadsen described.

This is typically called a "blonde transfer" as you shouldn't be using attended transfers as blind transfers; that's what blind transfers are for.

What does your dialplan look like so this can be reproduced? On the Local channel, do you have a /n at the end?
