long 1-4 interactions and Project 1487

[GTron]

I just completed 4 project 1487 WUs on a new folder and noticed on each the long 1-4 interactions warning in the FAHlog.txt even before the 0 steps message (see example below). The WUs eventually completed, and I was glad not to see the CoreStatus and client-core communication error messages that seem to usually follow, but thought it strange none-the-less. Is this a characteristic of this project or just a coincidence?

The 4 WUs:
Project: 1487 (Run 0, Clone 284, Gen 21)
Project: 1487 (Run 0, Clone 327, Gen 24)
Project: 1487 (Run 0, Clone 812, Gen 22)
Project: 1487 (Run 0, Clone 654, Gen 19)

This is "normal" for this project and won't cause the end of the WU (like it does usually) ...

[GTron]

Thanks toTOW!
It seemed a little too weird to be normal, but to have all 4 be a coincidence seemed even weirder, hence the question. I'm glad it's only weird...I mean "normal"!

and as you can see from last lines of the logfile, now it looks like it is folding alright.

What exactly is project 1487? It's rather large and taking quite a long time to move 1%. I'm hoping the point value is worth it.

The project lookup page says it's a new project and stay tuned :\

Nice! I have 2 or 3 or those chugging along. Anyone know what this project deals with though? Rough description or anything?
