[GitGab19]

Is there an existing issue for this?

Current behaviour

TP v.0.1.13 connected with a single client (JDC) for some days.

After 4 days (more or less) it aborted after the following error:

bitcoind: ./streams.h:76: void VectorWriter::write(Span<const std::byte>): Assertion nPos <= vchData.size()' failed.`

Expected behaviour

It should not abort.
