128.143.199.96 choking on upload [SMP on classic server?]

[ThunderRd]

I don't know why, but recently I have been receiving SMP WUs from this server, which the system labels as "classic", and maintained by Peter. It hasn't been a problem, WUs come and go. Today, a finished WU upped and the download stalled. Several restarts of the client yielded the same result. I downloaded the latest client [I had been using 6.30] and updated it to 6.34 with the same results. It stalls each time as you can see in the log.

I checked the server status page; the server is showing status "accept" which indicates the following: "When a server is in "accept" mode, it will accept WUs, but not give any out. Some servers are used for internal testing of F@H and might seem unfamiliar. "

Before anyone tries to suggest the basics, let me say that this machine has been running for over 4 years and has turned out many thousands of SMP units. No changes have been made to its configuration.

EDIT: Interesting. Shortly after posting this, I had a brain fart and forced a core a3 download. The client immediately jumped onto server 171.64.65.54 and downloaded a project 6020 WU, so for now, the box is crunching on that one. I do wonder why the client has been connecting to the other server, though. Here is an example:

For a while, SMP servers were unique and only managed SMP projects. I've noticed that newer servers seem to manage both SMP and Uniprocessor projects so my guess is that the designation of certain servers as SMP is going away and soon they'll all be called classic. I've seen no trend to combine GPU servers with classic servers, but since we're rapidly moving toward a unified client (apparently that's what V7 is) maybe we're also migrating toward a unified server. If so, the second column of serverstat.html may disappear.

I can't shed any light on your problem, though.

The new A4 core has blurred the lines of what is classic and what is SMP. It can run as either 1 core or multi-core. And like Gdub said, V7 will probably do more blurrrring.
