Event broker module - querying host/service/hostgroup...SIGSEVs

Guys,
I've been playing with the helloworld module and the inserter modules
from the nagios-db code to try to get something functional. I've put
together a function registered via:
neb_register_callback(NEBCALLBACK_TIMED_EVENT_DATA,nagiosdb_module_handl
e,0,loadConfig);
The function starts off with the following initialization...
static int loadConfig(int cmd, void *data){
host *hl;
service *sl;
hostgroup *hg;
hostgroupmember *hgm;
int groupcount;
char temp_buffer[1024];
char q[1024];
.
.
.
I have for-loops which query the host_list, service_list and
hostgroup_list lists. My problem is that I am getting SIGSEVs when the
following code inside this function runs:
/* Get current hostgroup_list from configuration */
for(groupcount=0, hg = hostgroup_list; hg; hg = hg->next)
{
/* update this service */
char *groupName, *groupAlias, *hostName;
groupName=hg->group_name;
groupAlias=hg->alias;
/* insert this hostgroup */
snprintf(temp_buffer,sizeof(temp_buffer)-1,"nagiosdb-efm: found
group %s with alias %s",groupName,groupAlias);
temp_buffer[sizeof(temp_buffer)-1]='\x0';
write_to_all_logs(temp_buffer,NSLOG_INFO_MESSAGE);
if(groupAlias) free(groupAlias);
for(hgm = hg->members; hgm; hgm = hgm->next)
{
/* add this host to the hostgroup */
hostName = hgm->host_name;
snprintf(temp_buffer,sizeof(temp_buffer)-1,"nagiosdb-efm
: found host %s belongs to group %s, with groupid
%d",hostName,groupName,groupco
unt);
temp_buffer[sizeof(temp_buffer)-1]='\x0';
write_to_all_logs(temp_buffer,NSLOG_INFO_MESSAGE);
if(hostName) free(hostName);
}
if(groupName) free(groupName);
if(hgm) free(hgm);
groupcount++;
}
snprintf(temp_buffer,sizeof(temp_buffer)-1,"nagiosdb-efm:
configured %d
groups", groupcount);
temp_buffer[sizeof(temp_buffer)-1]='\x0';
write_to_all_logs(temp_buffer,NSLOG_INFO_MESSAGE);
If I comment the above out, and run the other queries to the lists, no
SIGSEVs:
for(groupcount=0, hl = host_list; hl; hl = hl->next)
{
/* update this host */
snprintf(q,sizeof(q)-1,"nagiosdb-efm: Host %s found, has
followi
ng characteristics\n"
"checks_enabled %d, "
"accept_passive_host_checks %d, "
"event_handler_enabled %d, "
"flap_detection_enabled %d, "
"notifications_enabled %d, "
"failure_prediction_enabled %d, "
"process_performance_data %d, "
"obsess_over_host %d, "
"should_be_scheduled %d.",
hl->name,hl->checks_enabled,
hl->accept_passive_host_checks,
hl->event_handler_enabled,
hl->flap_detection_enabled,
hl->notifications_enabled,
hl->failure_prediction_enabled,
hl->process_performance_data,
hl->obsess_over_host,
hl->should_be_scheduled);
q[sizeof(q)-1]='\x0';
write_to_all_logs(q,NSLOG_INFO_MESSAGE);
groupcount++;
}
snprintf(temp_buffer,sizeof(temp_buffer)-1,"nagiosdb-efm:
configured %d
hosts", groupcount);
temp_buffer[sizeof(temp_buffer)-1]='\x0';
write_to_all_logs(temp_buffer,NSLOG_INFO_MESSAGE);
What am I doing wrong with the hostgroup, hostgroupmember which causes
the SIGSEV?
My eventual goal is to dump this to a database, but right now I'm
dumping to the nagios.log file to make sure the data makes sense. The
destination database is an ODBC connected DB (MSSQL to be exact).
Anyhow, appreciate any leads which can help me...
