Hi,
Thanks for the replay.
This is an example code of the first_data_point function of one of the
tables :
netsnmp_variable_list *
connectionToDBSTable_get_first_data_point(void **my_loop_context,
void **my_data_context,
netsnmp_variable_list *
put_index_data,
netsnmp_iterator_info *mydata)
{
netsnmp_variable_list *vptr;
int i = 0;
if(pMIB)
{
pMIB->connectionDBS[0].index = 0;
pConDBS_m = &pMIB->connectionDBS[0];
i++;
while(i < SHM_MAX_NO_OF_AMS && pMIB->connectionDBS[i].dbs_num !=
MAX_ENTITIES_NUM){
pMIB->connectionDBS[i].index = i;
pConDBS_m->next = &pMIB->connectionDBS[i];
pConDBS_m = pConDBS_m->next;
i++;
}
pConDBS_m->next = NULL;
pConDBS_head = pMIB->connectionDBS;
*my_loop_context = (void *)pConDBS_head;
*my_data_context = (void *)pConDBS_head;
vptr = put_index_data;
snmp_set_var_value(vptr,
(u_char *)&pConDBS_head->index,
sizeof(int));
return put_index_data;
}
else
{
return NULL;
}
}
I have removed the part of the code that checks if the table is empty
and returns a NULL because
this what causes the endless loop.
pMIB is a pointer to a shared memory. pMIB->connectionDBS is an array in
the shared memory that holds all the items of a certain table. In every
get request, I create a new linked list from the array that holds all
the items of the current table. The while loop runs till it finds an
initialized item.
(e.g. array[1,2,3,2,4,7,1,3,MAX_ENTITIES_NUM,MAX_ENTITIES_NUM...] so the
linked list would be 1->2->3->2->4->7->1->3->NULL). Basically there
should be an if clause that checks if pMIB->connectionDBS[0] ==
MAX_ENTITIES_NUM and return NULL for empty table.
Let me know if you need other parts of my code.
Thanks

Unfortunately, it's unlikely we can help you without looking at the
code you've written. It certainly is related to how you're handling
your code because the agent itself shouldn't be suffering from any
issues related to multiple requests in a single PDU.

It shouldn't matter.
