Hi Hans,
Assuming you tried this in an UML environment, can you share the backtrace?
B.T.W, i am not able to repordcue the problme even with writes a burst
of larger number of records.
Perhaps LOG is a slow receiver, will get back once you share the backtrace.
-AVM
but not able to reprodcue the the log server crash
can you please suggenst exat tescase whic logtest that writes a burst of
700 records with 5 us interval.
