corruption on table-footer (pos=2115454): bad magic number - now end in: invalid argument

[18300632 (snowy)]

After long running fine with syncthing (Ubuntu 14.04 32 Bit) syncthing v0.14.32 stopped today with panic logs As with other “panic” time, I restarted syncthing several times. As no solution, I deleted folder “index-v0.14.0.db” and restarted again. First it runs, but some minutes later it stopped again, now with

Use the search in the forum. There are plenty of posts covering this.

Hi, that’s not very useful answer

I searched for “invalid argument”, “bad magic number”, table-footer, but got no results covering my issue

what are the search you did to get plenty of post with solutions? Maybe one of it should stick at top of forum, if this error happened quite often.

For my situation I deleted database again and again and again and… After a lot of time it starts working again. Why I don’t know, but at the moment no panic logs anymore

“Corruption” is a good search term, or “panic” in combination with “database”. Your log extract is not the Syncthing log but something database-internal, making it less useful for things to search for.

Short answer: this should never happen and it’s likely you have a hardware problem corrupting the files on disk or in memory.
