Hi,
I'm using heartbeat 1.2.4.
When I use try to start hbagent, the following happens:
init_membership() in hbagent.c calls saClmInitialize in the ccm library
(ccmlib_clm.c) ...
saClmInitialize uses oc_ev_set_callback to register its function ccm_events
as a callback function.
The ccm_events callback function is the function which sets up the
__ccm_data pointer with a non NULL value.
Next, in init_membership(), the ccmlib_clm.c function
saClmClusterTrackStart is called.
It does the following:
const oc_ev_membership_t *oc;
...
...
oc = __ccm_data;
itemnum = oc->m_n_member;
However,
The problem is that this callback function "ccm_events" is never being
called, so __ccm_data remains as a NULL pointer....
and the "itemnum = oc->m_n_member;" causes a segfault (Normal for
referencing a NULL pointer :o))
--------------------------------------
send_message In ccmclient.c print the following :
"ipc channel blocked"
-------------------------------------
In /var/log/messages, I get the following:

-------------------
Does anybody know of a reason why ccm would not call the callback function
"ccm_events" ??
Is this todo with socket permissions or something ?
Thanks in advance,
Tony
