Description of problem: pppd loops in its main loop in main() if program supplied as pty argument terminates and 'persist' option specified . It traced that to fsm_lowerdown() for f->state=OPENED setting f->state to STARTING. as a result, when on a next iteration cycle we get to lcp_open()->fsm_open with this f->state, we do not bring our pty program up again (as we would do if f->state was INITIAL), so the pty is not setup, we exit lcp_open() and do another iteration in the loop, and so on and so on. Version-Release number of selected component (if applicable): ppp-2.4.3-6.2.1 (from FC5) How reproducible: 100% reproducible Steps to Reproduce: 1. configure pppd to use e.g. pptp as a pty script 2. start pppd with persist option 3. kill pptp 4. watch pppd eating 100% cpu. Expected results: I would expect pppd to restart pptp and connect normally to server again.
I see a similar thing with DSL here (PPPoE), when doing "ifdown ppp0; ifup ppp0" -- which I need to do despite the persist option (which should cause pppd to automatically reconnect to my provider after they disconnect, which they do every 24 hours).
Please verify this with the ppp-2.4.4 package from FC-6?

I don't have the problem with ifdown/ifup anymore, but I'd have to check (i.e. wait) to see whether it survives the disconnect after 24 hours. Oleg?
Unfortunately, I have nowhere to test this anymore, I stopped using pptp setup a while ago now. Sorry, I cnnot be of more help.
Thanks for the update.
