Dave,
Sorry about missing the reply all button.
I have migrated to using net-snmp 5.3.0.1 as suggested, however I
am still seeing the same memory growth.
There must be something that I am missing, something that I need to
free?
I have changed my code to look something like the following to
listen for traps on port 7878:
static int
pre_parse(netsnmp_session * session, netsnmp_transport *transport,
void *transport_data, int transport_data_length)
{
return 1;
}
static netsnmp_session *
snmptrapd_add_session(netsnmp_transport *t)
{
netsnmp_session sess, *session = &sess, *rc = NULL;
snmp_sess_init(session);
session->peername = SNMP_DEFAULT_PEERNAME;
session->version = SNMP_DEFAULT_VERSION;
session->community_len = SNMP_DEFAULT_COMMUNITY_LEN;
session->retries = SNMP_DEFAULT_RETRIES;
session->timeout = SNMP_DEFAULT_TIMEOUT;
session->callback = OnTrapRec;
session->callback_magic = NULL;
session->authenticator = NULL;
sess.isAuthoritative = SNMP_SESS_UNKNOWNAUTH;
rc = snmp_add(session, t, pre_parse, NULL);
if (rc == NULL) {
snmp_sess_perror("snmptrapd", session);
}
return rc;
}
void GetTraps(void* magic, int port)
{
init_snmp("Test");
netsnmp_session* ss = NULL;
netsnmp_transport *transport = NULL;
transport = netsnmp_tdomain_transport("udp:7878", 1, "udp");
ss = snmptrapd_add_session(transport);
if (ss)
{
int numfds = 0;
fd_set fdset;
FD_ZERO(&fdset);
struct timeval timeout;
timerclear(&timeout);
int block = 1;
for (;;)
{
snmp_select_info(&numfds, &fdset, &timeout, &block);
int count = select(numfds, &fdset, 0, 0, 0);
if (count > 0)
{
snmp_sess_read(&fdset);
/* free something here? */
}
}
}
snmp_close(ss);
snmp_shutdown("Test");
}
int OnTrapRec(int op, struct snmp_session *session, int reqid,
struct
snmp_pdu *pdu,void *magic)
{
std::cout << "OnTrapRec" << std::endl;
/* free something here? */
}
