Thanks, resolved.
I ran into the following libqb issue:
https://github.com/ClusterLabs/libqb/issues/139
https://github.com/ClusterLabs/libqb/pull/141
Applying 7f56f58 on libqb 0.17.1 fixed my problem.

hi,
I've built a recent cluster stack from sources on Debian Jessie and I
can't get rid of cpu spikes. Corosync blocks the entire system for
seconds on every simple transition, even itself:
drbdtest1 corosync[4734]: [MAIN ] Corosync main process was not
scheduled for 2590.4512 ms (threshold is 2400. ms). Consider token
timeout increase.
and even drbd:
drbdtest1 kernel: drbd p1: PingAck did not arrive in time.
My previous build (corosync 1.4.6, libqb 0.17.0, pacemaker 1.1.12) works
fine on this nodes with the same corosync/pacemaker setup.
What should I try? It's a test environment, the issue is 100% reproducible
in seconds. Network traffic is minimal all the time and there is no I/O
load.
