INFO: NMI handler (perf_event_nmi_handler) took too long to run: 2.816 msecs
I'm running Debian 8.1 on the smallest (5€) node and I'm getting perfeventnmi_handler messages to log file:
INFO: NMI handler (perfeventnmi_handler) took too long to run: 2.816 msecs
Server is running sshd and postfix on a very minimal (0.00, 0.01, 0.05) load. What error message means and how can I fix it if necessary or suppress?
