I've got little doubt that the mere ''upgrading'' is enough to flush the [BOINC] DNS caches, but going to 6.10.58 is perfect. Makes support easier, for that's the code-base WCG knows intimately and was tested extensively. At that, 6.10.17 had a benchmark flaw... often way too low [which with the server 700 implementation is mostly ignored].

Crunch On

--//--

3112 - scheduler: zero host.nsame_ip_addr if IP addr differs from previous

Indeed that was the problem for me. I stopped the boinc service, axed the client-state* files restarted and almost immediately started getting workunits downloaded again. Sadly the IP address that had changed from the address which was recorded in these files wasn't even for the adapter that handles traffic for WCG.

Hence the oft used: Since you (the computer technician) were here yesterday, what did you do to make the dishwasher stop working? You must have changed something because it worked before you arrived!

I've been monitoring myWUs and my wingWUs on account of this thread covering the matter of cruncher-reported failure initially cruncher-associated with the WU-downloading_process. On myWUs: no issue.

On my wingWUs, after the uplinger [Mar 29, 2012 8:19:19 PM] post datime, I get only one wingWU with an error for a statusReport, which error may or may not have anything directly to do with the issue on hand:

1]

Notes:
a] I was expecting a TME ("too many exits") in wingWU#1 errorReport above, TME being the predominant stated errorExplanation I've been seeing lately from my wingWUs errorReport -- but there was no stated errorExplanation this time.
b] BOINC_v6.10.17 is indicated as figuring in a majority of my wingWU's TME errorExplanation (days before the datime of the uplinger post).
c] All times in none-DST utc.

I agree with SekeRob, if you are running a version less than 6.10.58 as recommended on our site, then please update. There are multiple fixes involved with this as well as some security fixes.

Thanks,
