Use IE connection settings: Yes

Change this to No and it'll work better.

Both server can't be accessed via browser.171.64.65.111:8080 is time out,171.67.108.17:8080 is an blank page

This was written two years ago. How come exactly the same problem occurs nowadays (just checked)? I can't believe the problem could not be identified since 2008, or even last two weeks since Vijay wrote they'll look into this. I would think that once it is identified it should be also eliminated, sad to see it is not the case ...

Because these servers are a single point of failure .. this has been going on for quite some time now .. remember we are dealing with a academic institution and not a corporate entity .. PG doesn't have the ability to provide a constant flow of work to all platforms .. with a DC effort this big, I still don't understand why there is no adequate backup strategy in place for when servers go offline.. rolling over to collection servers when work servers go down isn't cutting it.

Stick with SMP2 and GPU2 clients .. work is always available and the servers are reliable.

It's a shame but the little guy with older machines doesn't get serviced properly .. if you have a quad or video card you're fine .. if you have machines older than a few years, forget it.

I am on Fedora 12 and cannot use GPU or SMP clients any more. Still waiting on an update to the client. So I downgraded to the classic client. Now all my machines have WU to upload and nothing to download. Total standstill. Happy Easter to my machines!

The whole point of the Collection servers was to provide the exact backup strategy that you suggest. It worked reasonably well but the server code was old and poorly written so they contracted for a complete rewrite of the server code. Apparently there are compatabilty issues between the new server code and the code on the collection servers because it was just about the time that they started rolling out the new server code that a number of new problems arose with the collection servers.

Unfortunately with a large number of servers, which limted staff, and with a need to keep FAH running 24x7x365 it's not possible to upgrade all the servers simultaneously so until they finish the roll-out of the new code, I expect that they'll keep having problems.

Another choice would be to shut down all of FAH for a week or two and update everything simultaneously, but that wouldn't make any of us happy, and it has the potential of shutting down FAH even longer if problems are discovered after all of the servers are upgraded. Even in a business environment where there are often a number of people with the responsibility to upgrade PCs, they don't switch all PCs from XP to Vista on a single weekend.

rolling over to collection servers when work servers go down isn't cutting it

Especially when the collection server doesn't work either (171.67.108.17 is listed as collection sever 4).

BTW thanks for the explanation codysluder, interesting though that you write "It worked reasonably well but the server code was old and poorly written so they contracted for a complete rewrite of the server code". Apparently it wasn't THAT poorly written since it worked well, so why change it? Out of aesthetic reasons? There is a couple of sayings on that, like "the better is the enemy of the good" or "you don't switch your horses in the middle of a ford":)

I downgraded to the classic client. Now all my machines have WU to upload and nothing to download. Total standstill. Happy Easter to my machines!

Now that's interesting, I downloaded today a 2613 without much fuss. Maybe try to play with your config some (for example change " -advmethods").

Can anyone confirm if 171.64.65.111 is offline/rejecting for good? - it's been offline all w/e by the looks of it - will the results still be uploaded okay if it does come back?
Cheers.

Still down i guess. Here's mine

Perhaps this is why.
