I also see this for tests with small output, but it happens more
often for tests with big output.

Not always, but usually. It seems related to how busy the system is,
but that could be my imagination.
It usually happens for a bunch of tests at the same time.
Not always is the output just cut short: some random characters
are inserted sometimes (in the individual log files, the consolidated
log file does not have those; it looks like pointers).
