>          Components: Core/General

>         Environment: OpenBSD 5.5 -- any kqueue(2) system; possibly Linux inotify too (but uncertain).

> This is a file descriptor leak.  Inodes tracked to TZ data files.
> Had Asterisk 11.7.0 (OpenBSD 5.5 ports) running about three and a half weeks before call failed.
> Triggered by any changes causing an event in the 'inotify' thread implemented in main/stdtime/localtime.c. This might not become apparent for most users, but my asterisk runs on a host using a DHCP client, the dhclient regularly rewrites /etc/resolv.conf, and this triggers a file event because /etc/localtime is watched, it is a symlink, and the kqueue(2) code actually watches the directory of a symlink.
> I have a fix on my system: although the last change is only running a couple of days, I had been able to trigger the bug at will -- e.g. chmod a TZ data file being watched, or create a file under /etc, and then vmail to trigger the time formatting code -- with the fix I can't trigger the bug at all.
> In the URL field of this form I put a http URL to a patch against 11.7.0 and
>  in "Reference Notes" that patch, and 11.15.0 and svn trunk of Jan 26 too.
