Re: [hylafax-users] faxgetty hangs



Lucie,

Please set:

TracingMask: 0x11
SessionTracing: 0xFFF

in your modem config file, restart faxgetty, and then send the log that gets stuck.

Your strace really looks like it's talking about a driver read block, but the session log with that verbosity should give us some clear indication.

Thanks.

Lee.

Hello,

I'm experiencing a problem since i upgraded to hylafax 4.2.1 on a server that had been running hylafax 4.1.7 on Slackware 9.0 without any problems. the modem is a gnet md0340, which i use on a few different sites and it works just fine. configs are defaults for class 1 except for PPM TCF EOP wait cmds and Class1SwitchingCmd that are set to <delay:n>

the fax answers most incoming faxes without problems, but approx. once a day it hangs, and i have to kill -HUP it to get things back up.

when it hangs, faxstat still thinks it is receiving, the log file c000XXX.log is stuck receiving frames
if i try to strace on the hanged process i get :
12:17:37.482728 time(NULL) = 1108574257
12:17:37.482776 time(NULL) = 1108574257
12:17:37.482827 read(7, <unfinished ...>


I really would appreciate some directions as to where to look.

this is a full log:
