What does the error "cman_get_cluster error-1 112" mean?

Issue

• In the /var/log/messages file we have a lot of cman_get_cluster errors (cman_get_cluster error-1 112). It appears that the error is a part of the code that checks whether the incarnation numbers of cman members are still consecutive.

+   rv = cman_get_cluster(ch, &info);
+   if (rv < 0) {
+       log_error("cman_get_cluster error %d %d", rv, errno);
+       /* keep going, this is just informational */
+       memset(&info, 0, sizeof(info));

Is this error a warning only? Is it a precursor to a real problem? Is there a way to prevent it?
