There are two feeders working, one feeding odd-numbered resultIDs, the other even. That change from a single feeder was implemented so if one feeder slowed down, the other would likely still be working well and continue to make work available.

WUID 136338500 illustrates one of the side effects. The even feeder is about 38 hours ahead of the odd feeder, so the one even result in that set was completed and reported about 31 hours ago, the two odd results were only sent out about thirty minutes ago. Check your pending credit list, most are probably cases where you got an even result like that.

The opposite case, where the results have two even and one odd number, should lead to many cases where the two evens complete and validate in less than 38 hours. The odd will then transition to "Not needed" without ever being sent out, a beneficial effect.

I've got one that has been returned and neither of the other two has even been sent yet.

Units still in my account since 00:01 21 June.

Units processed

Initial issue 2, third not issued yet, Pending 6, Granted 3 (3rd not needed)

Initial issue 2, third issued, Pending 6, Granted 2 with two returned, granted 4 with all three returned.

Initial issue 1 (evens), odds issued, 6 pending, 16 granted with two returned, 6 granted with all returned.

Initial issue 1 (evens), odds not issued, 6 completed.

Observation, there 4 more units with a host error, the extra replication is odd in all cases. Question, is it just my luck or is this generic problem?

Units in my cache, all even issues only, i.e. less than 38 hrs old

9 WU where I am only recipient

12 WU where 2 copies have been issued.

Since dual splitter has been introduced my average pending gone from 800 +/- 400 to 1600 and is still rising as far I can see.

I've got one that has been returned and neither of the other two has even been sent yet.

The WU quoted above has now been sent to the other two hosts, some 15+ hours after I returned it.

Another one that I have returned that has not been sent to the other hosts.

http://setiathome.berkeley.edu/workunit.php?wuid=136897020 has been over 24 hours since it was sent to me. I just completed and reported it, still waiting for a Quorum partner or two!
