Hi,

I run avahi 0.6.31 on FreeBSD 8.4-RELEASE-p3 amd64 inside a VMware VM =
with vendor supplied tools installed (i.e. no emulators/open-vm-tools). =
Within a few hours up to a few days after restarting, avahi-daemon =
exists with "poll(): Invalid argument". I added some syslog() calls to =
avahi-common/simple-watch.c. Turns out that avahi_simple_poll_prepare(), =
line 506 can run into an integer wrap around when usec > 0x7fffffff. =
=46rom my debug output:

avahi-daemon[4447]: avahi_simple_poll_prepare: t:-2147308239 =
usec:6442626352642 ntsec:1390524436 ntusec:348696 nowsec:1384081809 =
nowusec:996054

(where ntsec/ntusec are next_timeout->expiry, and nowsec/nowusec are =
now)

Fixing this might be trivial (insert 'if (timeout < 0) timeout =3D 0;' =
at line 513), although I don't know why next_timeout occasionally is =
about 74 days in the future (no adjkerntz when avahi-daemon exists, no =
time leaps, vm behaves normally besides that avahi strangeness).

Anyone..? I can add additional debug statements to avahi and provide =
more data if asked for.
