Any fixes for the:

Code:

[2019-10-31 11:11:59] Started bfgminer 5.4.2-38-g106390aSegmentation fault

Haven't seen any responses. Just curious as now I have both miners just collecting dust, removed them completely out of my rig. As it's getting segmentation faults on every pool. Ran both on a Ubuntu and raspberry pi systems. It's been running flawlessly for months 24/7 on my raspberry Pi until just recently. Not sure why they are failing now unless this is a problem with the moon lander itself?

Have you run any updates on the Pi?
You might want to delete bfgminer and rebuild. From some minor research it looks like segmentation faults are often from build issues, though sometimes it is from missing dependencies on the OS. So I would try an update and reboot first and if that fails start from scratch. If you used the download from Futurebit I might redownload and unzip it to a different location.

Otherwise I have no clue...

Thanks I'll try rebuilding it. Haven't done any updates to that unit since everything has been working. I also run several Newpacs and R606's also on the same pi 4. I'll rebuild it into a new directory and see if that resolves the issue. I have another Pi 4 that's currently not being used, may give it a try on it as well. Just to rule out if something is a bit off on the rig it's currently running or not.

Thanks for the assist

Well finally got around to fully testing this. Still unsure why it's now messing up. These two moonlanders I have ran originally on a Raspberry Pi 3 and later Pi 4 without issue. About 6 months 24/7 on a Pi 3. I'm assuming since there have been some forced updates on the Raspberry Pi 4 kernel that it's possibly causing the Segmentation Fault errors? I have 3 pi's and have tested on all 3 of them. I've reloaded Raspbian and went lite, full buster and NOOBS editions, same results. It might run now for an hour or sometimes up to 8 hours but the miner eventually crashes with a Segmentation Fault. Sadly I am unable to find any prior release copies of Raspbian. The oldest copy I have is Noobs Version 3.2 that was released in July 2019. So I've only be able to back date my OS to that point with these tests.

I've now loaded them on my personal Windows 10 rig. They are running for now. I'll see if they will remain stable and if so I'll then just attach them to one of my GPU mining rigs (with powered usb hub). I'm assuming the links on the first page of this thread are still valid for the bfgminer software? So there hasn't been any updates since 2017? Just wanting to make sure I am using the right miner.
