Project 2653 Run 29 Clone 155 Gen 148 - Missing work files

[Adam2013]

I was folding along just fine (Project 2653 Run 29 Clone 155, Gen 148) until the client got all the way done with this WU. I happened to be checking Fahmon at the time so what I saw was this in the logfile:

It stopped the core and then I thought it was telling me to delete those two files because it couldn't. I did and then I got this error the next time I started that client:

If anyone has any information or needs more, please let me know. I have already accepted the fact that I will probably be losing this WU

Those messages should be ignored. One fundamental rule is that you should not manipulate any of FAH's files. The client is designed to run unattended and to correct whatever might keep it from continuing to work. There are a few cases where you can help it along, but there certainly a lot more cases where you can get into trouble, so it's best to do nothing.

You'll find those messages in many different situations. Here's one case where there was an error and another where the WU completed successfully. The important thing to note is that the WU is not actually completed until you get the CoreStatus = xx (yy) message. Stopping the client or manipulating any files until you get a CoreStatus message is risky, and in your case, caused the loss of a completed WU.

Thanks Bruce,
After I started my client, it took awhile but it started on a new WU. It seems to have trouble connecting to 171.64.65.56, but ill post to a different thread if it keeps happening.
