asterisk users - Oct 2006 - How big is *your* ego?

http://www.elna-america.com/tech_al_reliability.php 

Capacitors are one of the components on that motherboard that have a
finite life span.  Other components are more or less tolerant of these
changes over time.  Eventually the caps WILL fail...this could be 5
years or 25, but it WILL happen with electrolytics.  I have a well
maintained, regulated (3 phase power distribution all ups'd generator
etc.) and vented data center (72F 40% relative humidity year round) and
loose things once a week...typically hard disks, but power supplies
often.  I monitor and graph temperature PER SERVER.

Cpu's also in fact also have a limited life span due to
electromigration.  Keeping a processor cool certainly does slow this
process, but does not eliminate it completely.  This actually applies to
most IC's, but it is more significant in processors where the layering
process is extremely thin.

Often there is no symptom of these events before something critical
breaks.

I'm not siding with anybody here, but there is some glaring
mis-information in this thread.

P.s. I do work with a lot of un-pro (claimed) dell equipment, but also
hp9000, sun enterprise 10k, old as/400 f40, dec alpha, and yes, pix and
netscreen.  They all quit at some point!

You are telling me that it was: A. Well regulated B. Well maintained C.
good ventilation, and it died suddenly, without giving you any hints
before hand?
I just don't believe you, I might have on one machine, but I'm not going
to believe you since you said you seen it on every machine. BTW, have
you ever seen a machine that survived everything and was just taken to
the dump because it was outdated and wasn't needed anymore?

No they don't, they give some warnings like too hot.

Matt,

Thanks for the information and the Wikipedia reference.  We all
appreciate unbiased presentation of facts, even if we don't always
present them in an unbiased manner ourselves. :)

At this time no but if you'd like to know more about it see the following:

http://lists.digium.com/pipermail/asterisk-dev/2006-October/023810.html

At this time I won't be releasing the program since it has no purpose
other than crashing Asterisk and affecting other vendors' products.
If there were immediate fixes for it I would. If an SBC did any
justice against it, maybe. Right now I see no need to disclose the
program.

The staff at Digium were given access to the program email one of the
higher ups there see if they're willing to dish it out. I won't till
a fix is in place.
