This sounds like a Juniper-specific issue, so the appropriate place is 
probably going to be http://puck.nether.net/juniper-nsp/.

I have this problem where a customer of mine has issues getting to
secure websites (https sites like Charles Schwab's).  It doesn't happen
all the time, maybe once a month or so.  We went to Juniper with the
issue (we're using M-20s as our edge routers) and they couldn't figure
it out, but one of our engineers found that the config pasted below
(with proprietary info removed) fixed the problem.  The only problem is
that even with this config, we have to restart the sampling daemon every
month or so because the problem will come back.  Understandably, the
customer would prefer to have a more permanent solution.

You have to restart the sampling daemon to forward packets to SSL based 
websites? Wha? Are you sure you didn't accidentally install a Crackpipe 
Services PIC in that router? :)

Anyone have an idea why this one customer on my entire network would
have this issue?  Supposedly the customer had Cisco come out and look at
their network and they couldn't find any reason for it either.

Nothing in that config would cause or cure the problem you've described, 
unless the config it replaced was "from destination-port 443; then 
reject;". I suspect your problem lies elsewhere, which is why Juniper and 
Cisco both said there were no problems. :)

But if there really is something going on with the Juniper, re-post this 
to juniper-nsp (with more details about the failure behavior) and I'm sure 
someone will give it their best shot to figure out what your problem is.
