It happens every so often on my encrypted gdrive. Is it something I should be concerned about?

It comes from this bit of code in the cache backend

        // not found in ram or
        // the worker didn't managed to download the chunk in time so we abort and close the stream
        if err != nil || len(data) == 0 || !found {
                if r.workers == 0 {
                        fs.Errorf(r, "out of workers")
                        return nil, io.ErrUnexpectedEOF
                }

                return nil, errors.Errorf("chunk not found %v", chunkStart)
        }

So I don't think it is a serious problem and it should probably fix itself the next time I guess.

ok, makes sense, placing a load on it, timeouts could be expected.
