Error packing file

[Matthias Teege]

Hi,

I'm synching data between two perkeep servers using "pk sync --src
remote --dest localhost". Occasionally, errors occur in the process.
The server issues messages like this:

blobpacked: 2019/06/29 12:31:28 Packing file sha224-afebc65a7765cc825612420345be225df24e4670e2b0e2965ebecd56 ...

$ perkeepd -version
perkeepd version: master, 2018-09-27-ae7698101e+

$ perkeepd -version
perkeepd version: master, 2019-05-23-8e630505c8

How can I fix this problem?
