Errors and varying/very low PPD on 16945 (12, 3, 1)

I am noticing a PPD value for this WU of between 1/5 and 1/10 of my usual, and there are a couple of errors in the log:

I don't know what the Broken pipe refers to, but something is wrong, besides wildly varying TPF, and over all very slow progress.

Also a unit ID of 0 seems fishy:

Code: Select all

01:48:51:WU01:FS00:0xa8:Project: 16945 (Run 12, Clone 3, Gen 1)
01:48:51:WU01:FS00:0xa8:Unit: 0x00000000000000000000000000000000
Especially since earlier it lists a different (non-zero) ID:

Code: Select all

01:48:14:WU01:FS00:Download complete
01:48:14:WU01:FS00:Received Unit: id:01 state:DOWNLOAD error:NO_ERROR project:16945 run:12 clone:3 gen:1 core:0xa8 unit:0x00000003
00000001000042310000000c
Has anyone else seen something similar in this project or others?

Cheers,
HG.

Unit ID of 0 is a red herring... it's correct that previously, there was a valid Unit ID but that feature has been depreciated and future versions of FahCore will not have them. Consider this a temporary cosmetic issue.

I think that "Send error: 32: Broken pipe" is related to FAHControl but don't know the cause/fix for that.
