[hylafax-users] segfault

[Craig McLaren <craigmc@xxxxxxxxxxxxx>]

Hi All,

Currently we are running the Hylafax package on Ubuntu 10.04. Modem is
a USR 5637.  99 times out of 100 it will receive faxes OK.  On
occasions modem will hang and Hylafax will not answer incoming calls.
At the same time the modem hangs \var\log\messages will show:-

Restarting Hylafax seems to clear problem.
