This issue is solved now: the check_ssh doesn't send a '\n' at the end of
its performance data, other check_* do. Thus the fifo_write-bug didn't
break a lot, just created an additional single 'n' on a line itself. 
Except for check_ssh.

This way each performance output directly after the output from
check_ssh wasn't processed, because collect2.pl read a single line,
containing first the ssh *and* then the other performance data.
