lnd 0.9.1 crashing on raspberry pi #4052
Comments

Could you paste a bit more of the lnd log? I think it's located somewhere like |
|
Yeah sure. log of lnd has the same content except for the systemd stuff. |
|
11/SEGV means, as far as I know, that lnd tries to access memory which is not assigned to lnd. Which should be a bug of lnd. |
|
Hmm... It's really hard to tell what exactly went wrong as there is no stack trace. It indeed looks like the OS kills the process because of a segmentation violation. |
|
Yeah sure, I can try that if you could provide me a binary for linux armv7 built with go 1.13 |
|
After testing 0.9.1 built with go1.13 I figured out that no crashes appear anymore. I'm not sure what the problem is but I can confirm that a binary built with go1.13 works like a charm. Tested on armv7 (raspberry pi). |
|
Current suspect is some asm code in @turcane was able to reproduce the bug on a second Raspberry Pi. He also volunteered to try running a binary compiled with |
|
bingo. this was the problem. after more than 1 hour runtime on two raspberries no crashes anymore. great job! |
|
Can confirm this error with using a RPi4 4GB with RaspiBlitz v1.4 upgraded to lnd v0.9.1 (running well on v0.9.0): Also reported by @kilrau: openoms/lightning-node-management#6 Will compile from source with Go 1.13 and report. |
|
Unfortunately experienced the same after running for ~10h even if compiled from source with the v0.9.1 tagged commit on Go v1.13.3 : |
And after two days? @turcane |
|
i can confirm that my raspi3 with release version 0.9.1 also crashes after some minutes/hour, version 0.9.0 works. |
|
Do y'all have the |
|
When running without systemd all I get after the usual LND [DBG] PEER outputs is: and exit |
|
unfortunately the same for me with the 0.9.1 version. I installed 0.9.0 again yesterday and so far no crashes. if you want me to test any version, just let me know :) |

In this commit, we update to a new version of `x/crypto` that drops broken ARM assembly that can cause a segfault in systems like raspis. The broken assembly was removed in this commit to the runtime: golang/go@8b77410. Fixes lightningnetwork#4052.

Can y'all try out this branch to see if it resolves things? https://github.com/lightningnetwork/lnd/tree/v0.9.2-beta-rc1-branch It includes one commit on top of |
|
ok, running with the commit b96de11 Will report if still up after a day. |
|
I encountered a similar problem on an odroid-hc2 (architecture: armv7l) with lnd version 0.9.1 failing with a segmentation fault as well: |
Had no issues since with the updated library, the problem is likely solved, since it is the longest uptime with lnd v0.9.1. Folks running a RaspiBlitz setup can use this script to test: Paste the commit hash: |

@openoms dope! If over the next day or so, we don't get a conflicting response, we'll cut |

We've tagged the new version: https://github.com/lightningnetwork/lnd/releases/tag/v0.9.2-beta Binaries are uploading as I type this, will then have the usual release notes template albeit it'll be much smaller (only a single change). |
