Re: possible regression with pty.c commit

[Sergey Senozhatsky]

Hello Alan,
I'm having another problem which I guess may be caused by pty/tty changes.
The problem is that ppp connection constantly hangups under load (downloading) 
(it works perfectly with 30 kernel).

syslog:
pptp[1942]: anon log[logecho:pptp_ctrl.c:677]: Echo Reply received.

pppd[1929]: No response to 4 echo-requests
pppd[1929]: Serial link appears to be disconnected.
pppd[1929]: Connect time 8.5 minutes.

In average it works ~10 minutes. 
I did "strace -ff -F -tt -s 200 -o ... pon ..." which produced 11MiB and 46 files (it'll take some time to dig).
Do you have any ability to test ppp under load?

	Sergey
