Hi Frank!

First, which OTP version are you using?
Second, try that on a fresh minor release — some scheduler issues were
fixed recently.
Third, try rebuilding OTP with ./configure
--with-microstate-accounting=extra and
check what are these schedulers doing (which columns have the most %)

This could give some more valuable info.

Also you may check which processes are using lots of scheduler time. Try
using etop.
After you find troubled processes, you may use fprof to determine which
functions are slow. In simple case you can just see that in
process_info(Pid, current_stacktrace).

Good luck!
