[Pacemaker] Where is MAXMSG defined?

Yes, found it where you said it was. I haven't search cluster-glue, I
didn't imagine it would be there.

The reason I need it, was to increase its value because I disabled the
bz2 compression (don't know if I did it right either... do you have
any sugestions on how to disable the bz2 compression and if it has any
positive impact on the cluster's convergence?) trying to increase the
performnace of a cluster with
100 primitives. After disabling the compression, I got the following
in the log and thought that I can solve it by increasing the MAXMSG

I didn't had a chance yet  to check how it works after increasing
MAXMSG to 512, I'll try to get back on this after testing.
