RE: Table's String index does not work

Hi
Running snmpd under debugger gave the following error message:
*** glibc detected *** /usr/bin/snmpd: free(): invalid next size
(fast): 0x00000001201532a0 ***
Aborted
I have also noticed that the index of the next value that was brought
get's cut:
./data/net/naamab/snmpgetnext -m ALL -M
/data/sw/snmp/snmp_mib_lnk/ -v 2c -c private 127.0.0.1
1.3.6.1.4.1.37576.4.1.4.1.1.3.\"committed-switch\"
NOVELSAT-DEMODULATOR-MIB::nsDemodConfigDiseqcNumDataBytes."non-committed
-sw" = Gauge32: 1
===> when the index value should actually be "non-committed-switch" (not
to be confused. I am doing getnext to "committed-switch" in order to get
"non-committed-switch")
Inner log prints show that at the end of get_next_entry function index
has un-cut value: idx->val.string=non-committed-switch
I attach both mib and c file.
I don't understand which FREE can cause the crash...
Thank you,
Naama

If the agent has crashed, then that is to be expected.

as is that.
If the agent is no longer running, do you really expect it to
respond to subsequent requests?

We have no way of telling.
You will need to do some deeper digging to find out.
Have a look at the project wiki pages on debugging for some advice.
As a starting point, try running the agent under a debugger (using the
options '-f -Le'), and send the same GetNext query.
That should at least tell you where the problem is being triggered.
