Ok, thank you for the quick reply!

I am running a R-Box with BFGMiner and getting an error pretty frequently:

"No task Request? Probably lost, Resending task X"    where X can be a 0 or 1. 

I am running 4.6.0 on Windows 7.  I am running a second instance of BFG which is mining with Antminer U2s and I have yet to see the error with those.  Just seems to happen with the R-Box. 

I did some searching and couldn't come up with any fixes.  Any ideas?

I have the same issue on 4.5.0, U1 and U2s run fine, RBOX has a lot of errors.

I don't seem to have too big of an issue with HW errors.  I am holding steady at .81%.  My biggest concern is that when the Task error appears, my hashrate drops significantly.  The issue seems to crop up every 20 minutes or so.  I am on Ghash as well.  I wonder if it is a network based issue?

That's just a fact of life with R-Boxes

Thanks for the quick reply.

GUESS WHAT I SMELL!!!

spondoolies support is a-coming!!!!!!

[ManeBjorn]

The do test it out from what I understand.  I should have asked Zvi when I interviewed him.

luke with in the last 24 hrs has posted a branch named minergate

[ManeBjorn]

I saw that.  This can be big.
It it performs better on the SP30 than cgminer you know Zvi will have it in there in a heartbeat.
My SP30 review is in the pending pile at CCN and I got to interview Zvi quickly for it as he was massively busy.
Pretty cool stuff.

Unlikely, since the minergate driver is just using Spondoolies' minergate software, which does the actual driver implementation.
Will probably write another, standalone, driver eventually if it makes sense, but this was a quicker way to get things working at least

[Taugeran]

Hey what works work. Gotta have someplace for baseline

[Dustdevels]

im waiting for the technobit support as i have one of those pieces of shiat and would prefer to be able to run it with my other stuff at the same time then having like 2 or 3 different things running to to run the units i have

Gentlemen,

I can remotely crash bfgminer, core dump is 100% repeatable:

Code:

$ printf 'stats'  | nc bfgminer 4028

or

Code:

$ printf '{"command":"stats"}'  | nc bfgminer 4028

bfgminer is the latest from GIT running at older Ubuntu host and it is mining some SCRYPT coin with one ZEUS miner connected to USB port.

Other commands I tried work OK, like this one:

Code:

$ printf 'summary'  | nc bfgminer 4028

I found this problem when I tried to monitor this host...

Some debug example:

Code:

 
 [2014-08-16 16:17:01] ZUS 0aa: Got work 139 from get queue to get work for thread 0

This is fast and dirty workaround, I know it is bad but it address crashes and I can use miner API:

Code:

$ git diff -u api.c
diff --git a/api.c b/api.c
index 1bfd9bb..5aff5f3 100644
--- a/api.c

+                               extra = NULL;
                        else
                                extra = NULL;

This condition is part of a loop, bfgminer crashes when index j is 1 and it points to zeusminer driver, some structure is not initialized. Loop is run 48 times (or 8 times when zeusminer:chips=1).
My ZEUSMINER is Blizzard, it has 6 ASIC chips. I tried to add parameter --set-device zeusminer:chips=1 but it doesn't help...

I tried to solo mine a dead scrypt coin with low difficulty. I was the only miner and in few seconds I found 13 blocks, I can see them in the wallet. But I see that bfgminer reports, it detected 27 new blocks on the network. That is a bug in bfgminer, only 14 new blocks were there (13 blocks solved and one, the last one, unsolved). New blocks (NB:) and accepted blocks were seen in ncurses screen and I can see them in final report:

hallo Freunde ,

ich bin in dieser BFGMINER neu.Ich habe mir BFGMINER herunter geladen.Ich bekomme es zum  laufen aber wie mann das nennt arbeiten die Arbeiter nicht.Ich glaube habe Problem .

Kann mir bitte ein freund  da ein bischen hilfe leisten. Ich danke im voraus.
Ich bekomme immer dieses in Erscheinung.

Hello all,

I am using Minera with BFGMiner but I have noticed that BFGMiner is not letting me hash at full speed.  I only can get 70% of the throughput before getting hardware errors.
Additionally, I have noticed that BFGMiner taking up CPU load up to 3.5  I think there may be a bottleneck somewhere within BFGMiner that is causing this excessive CPU usage.

My Miners are 2 x Zeus Lightning X6.  I should be able to hit 84 MHs with both units... as per CGMiner.

I am using Minera with BFGMiner but I have noticed that BFGMiner is not letting me hash at full speed.  I only can get 70% of the throughput before getting hardware errors.
Additionally, I have noticed that BFGMiner taking up CPU load up to 3.5  I think there may be a bottleneck somewhere within BFGMiner that is causing this excessive CPU usage.

My Miners are 2 x Zeus Lightning X6.  I should be able to hit 84 MHs with both units... as per CGMiner.

Unfortunately we do not have access to this specific hardware to test. Can you test on a PC by chance?

I am currently running the CGMiner 3.1.1 with Zeus support from Zeusminers on an EeePC running Windows XP and it is working fine... I will try with BFGMiner once I download it for Windows.
