FYI,
no "Broken Pipe" errors in a long time, so today I increased the OsmocomBuild1 nr of executors from 3 to 4 ... and immediately got two subsequent openbsc builds hitting the "Broken Pipe" again.

This time I tried something else: lower the "make -j 9" to "make -j 3" and leave the nr of executors at 4...
Just dabbling, would be nicer to pinpoint the real cause.
