I get this panic message when I try to start syncthing in Debian. I had this before and had to completely remove syncthing from the system to get it to work, but now I have the same problem again. What is causing this?
make sure that all devices in your network use the same Syncthing version, e.g. 0.12.x

I’ve been seeing a similar error randomly since the upgrade to v12.x and only on my debian box…If I delete the database syncthing will start fine (but have to rebuild the db of course which is a fun wait).
panic: xdr read: bytes field exceeds size limit; 1338205133 > 64
That sounds odd - corrupt database, but why… What’s the full panic trace?
I am pretty sure you manage to connect to some node that has 0.11 and it crashes.
We shouldn’t panic from that though. The only panic: xdr read: ... I know of off hand are when reading stuff from the database which is supposed to be correctly formatted and we’re in very deep water if it isn’t…

Yeah, something bad there. I’d suspect disk corruption (bad disk or bad memory), but normally I’d expect that to be a checksum failure. Maybe leveldb only checksums the metadata.
Pretty much the same here…only 2 devices running syncthing and both are running v12…no problems before v12 but obviously that could be a coincidence

So the fact that you both have the exact same backtrace and likely error seems to point at a bug here. Just for fun, do you maybe have some quite long folder names?
No, that wouldn’t cause it anyway. I don’t know…
The longest top level folder I have in syncthing is only 7 characters…other folders and file obviously longer but nothing super long.
So that’s super weird. Can you guys please try the build from here once or twice:
http://build3.syncthing.net/job/syncthing-pr/1317/
It’ll act the same, but when this problem happens it’ll print “Woops, unmarshal error” followed by a bunch of hex data before crashing. That data may tell us what’s going on to cause this. It’ll include your file name and some hashes, so if that’s sensitive feel free to put it in a private message, but the data will be valuable if it can be shared…
I’ll give it a try. It doesn’t happen all the time, but seems like I’ve been resetting the db every few days so I’ll let you know when it happens again.
Thanks
I tried with the new build and got this log. Could it have something to do with the size of the share folder? Both versions are 0.12.X.

which looks fine right up until offset 0x80, which is where the second out of 25 block hashes should start, but instead we get a large chunk of zeroes, 128 of them to be exact, after which the block list continues. So it looks like 128 bytes in the middle of the entry (128 bytes into it, in fact) has been overwritten by zeroes… I’m not sure how that would happen yet.
@jonitor, @SenorLoco When this happens next, could you save a copy of the database before blowing it away? So that we can check it for corruption and maybe try to see if something’s happened to it there…
Where is the database located? Do you mean the files I am sharing?
The database is typically located at ~/.config/syncthing/index-v0.11.0.db (there will be many files in there, which together constitute “the database”). If you’ve specified -home when starting Syncthing, then your database will be inside wherever you specified.
