Does libqb pass make check with this change?
With Solaris the
tests with shared memory are disabled, so only the 7 tests are used.

==================
All 7 tests passed
==================
The errors don't occur when the tests from libqb are used.
I checked several sources from pacemaker with libqb-014.2 (release), libqb-014.1 (release)
and libqb-master from github.
These are the versions of pacemaker checked. NOK=with error, OK=without errors
git checkout 1f067dbff3 # 28.06.2012 NOK
get checkout 4789299a6b # 29.06.2012 NOK
git checkout 010a16b1c8 # 28.05.2012 OK
git checkout db5e16736c # 30.04.2012 OK
git checkout ee0730e # 28.03.2012 OK
The errors depend only on the version of pacemaker. Versions between 28.03.2012 and
28.05.2012 work with any version of libqb (with fixes for solaris!
Changes in pacemaker between 28.05.2012 and 29.06.2012 produces the errors.
Please note that the errors are only visible in Solaris/OpenIndiana.

We did a big amount of work on libqb/corosync portability in the last
2/3 weeks and this didn't appear to be a problem with git master.
Can you please confirm what you are using?

In Solaris/OpenIndiana qb_ipc_us_recv_at_most returns -ENOTCONN when a client
disconnects.
_process_request_ and qb_ipcs_dispatch_connection_request don't know this and log the
2 errors.
With this patch the logging is suppressed.
