Recently following error appeared in gerrit:

ERROR: testBSCreload (__main__.TestVTYNAT)

ERROR: testUssdSideChannelProvider (__main__.TestVTYNAT)

error: [Errno 104] Connection reset by peer

This can be rather reliably reproduced manually by running:

./configure --disable-iu --disable-mgcp-transcoding --enable-vty-tests --enable-external-tests
make check

Initially suspected b3e34435b3bde227805c8dcac39c28e57144e500 in libosmo-netif is unrelated: error reappers even with earlier libosmo-netif version. It could be that this is somehow related to I435aaa33605bd48635715a2c81aa2d231c1abf51 in libosmocore or maybe test expectations are wrong.
