[DRBD-user] "Assert" cause for concern?

[Steve Bourg]

I recently installed/configured DRBD 8.0 on a newly installed Gentoo pair. 
Functionally, everything appears to be working great.  However, my console 
and log files are filling with the message shown below on the Primary 
node:

Apr 22 09:24:41 arrogance drbd1: ASSERT( mdev->net_conf->wire_protocol == 
DRBD_PROT_A ) in /var/tmp/portage/sys-cluster/drbd-
8.0.0/work/drbd-8.0.0/drbd/drbd_receiver.c:3156
Apr 22 09:24:41 arrogance drbd1: ASSERT( mdev->net_conf->wire_protocol == 
DRBD_PROT_A ) in /var/tmp/portage/sys-cluster/drbd-
8.0.0/work/drbd-8.0.0/drbd/drbd_receiver.c:3156

DRBD_PROT_A ) in /var/tmp/portage/sys-cluster/drbd-
8.0.0/work/drbd-8.0.0/drbd/drbd_receiver.c:3156

This message is is written several times a minute under 
nominal/non-existent activity.  So far is has not caused problems for me 
but my activity has been lightweight and my logs are being flooded.  Does 
anyone know if this message is indicative of something to be concerned 
about.  If not, is there someway to just surpress it?
