[hylafax-users] multipe sendfax hanging

["Bernd Proissl" <lists@proissl.de>]

Hi everybody, 

after playing around with source code patching (4.1beta3 on Suse 6.2)
and mass faxing tests (a script which starts many sendfax concurrently)
I have multiple established TCP connections

linux1:~/hylaori/hylafax # netstat -an|more
Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address           Foreign Address         State
tcp        0      2 192.168.1.100:23        192.168.1.8:1033        ESTABLISHED
tcp        0      0 0.0.0.0:4559            0.0.0.0:*               LISTEN
tcp        0      0 127.0.0.1:4228          127.0.0.1:4559          ESTABLISHED

tcp        0      0 127.0.0.1:4226          127.0.0.1:4559          ESTABLISHED

.....

looks like sendfax is waiting for something

linux1:~/hylaori/hylafax # lsof -i tcp:4559|more
COMMAND   PID USER   FD   TYPE DEVICE SIZE NODE NAME
hfaxd   10067 root    4u  inet 551228       TCP *:hylafax (LISTEN)

x (ESTABLISHED)
sendfax 12056 root    4u  inet 511308       TCP localhost:3478->localhost:hylafa
x (ESTABLISHED)
sendfax 12074 root    3u  inet 511335       TCP localhost:3481->localhost:hylafa
x (ESTABLISHED)
sendfax 12074 root    4u  inet 511335       TCP localhost:3481->localhost:hylafa
x (ESTABLISHED)
...

Is there a way to diagnose now where sendfax is hanging? 

The system still works in this situation.

Bernd
