[asterisk-users] Extensions Reload | Asterisk Freezes ? 1.4

[Positively Optimistic]

Thanks for the response Mr. Madsen...

Typically we leave verbosity set at 20...  with debugging disabled. (0).  It
is a somewhat older version of asterisk..    and I don't follow the release
cycle too closely..    I'll go digging through the release notes and see if
I can identify any notes regarding this specific issue...

Is anyone experiencing this on a later release..?

We don't really see a point in upgrading unless it adds a feature or the
upgrade is known to resolve a problem.. upgrading for the sake of upgrading
hasn't been something we practice.... and, knock on wood, it's been
extremely stable with this one exception...  oh!! i forgot, DNS, or the lack
thereof, also tends to kill asterisk...  kill as in, freeze solid...., so,
with these two exceptions... it's solid as a rock..

Connected to Asterisk 1.4.16.1 currently running on sw0 (pid = 2421)

Verbosity is at least 20

Do you have a particular version this is happening on? Does it happen on all


versions? When you say it freezes up, does it happen for a long time, or a
short

time (i.e. are you restarting because you can't wait for it to finish
reloading,

or whatever it is doing)?



When you are reloading the dialplan, do you have verbosity enabled or
disabled?

I find calls can be locked from doing anything while the dialplan is
reloading,

and if you're doing it remotely with verbosity enabled, this can make it
take

longer than necessary.



If Asterisk locks up, perhaps it is some sort of deadlock. There is some
good

information recently added that should help you gather debugging information
if

you plan on filing a bug report (http://issues.asterisk.org)
