Santhosh,
Thanx for ur immediate response.
followed the same example - /examples/notification.c
snmp_free_varbind is called in our code after send_v2trap().
In top output, i can see the size remains same even after snmp_free_varbind()
is called.should size decrease after free is called?
For every 100 msec, callback will be called,snmp_varlist_add_variable() is used
to store the variables and send_v2trap() is called for sending a single trap.
I dont know how to create session / send all traps in a single session.
Thanx,
Devi.U

Hi Devi,
The increase shown in top is memory usage by the application; all
increased bytes might have not been leaked.
You need to free the varbinds after sending each trap/inform.
snmp_free_varbind(notification_vars);
refer: http://www.net-snmp.org/dev/agent/notification_8c-example.html
Print the "top" output after freeing varbind and check the usage.
Are you using single session to send all trap/inform or creating
session before sending each inform/trap?

Santhosh

Hi,
thanx santhosh..
I am able to purify the code..
I feel that memory leak is there when send_v2trap is called, but i am not
getting any MLK/PLK in traces
top display:
26760 root 1 0 19 9248K 5608K run 0:01 0.30% snmpd
top display after a trap is sent ===> for each trap sent there is a increase
of 40K in SIZE and goes upto 50M.
26760 root 1 0 19 9288K 5648K run 0:01 0.31% snmpd
we are using net-snmp version 5.3.0.1.
whether above increase in SIZE is memory leak?
Thanx,
Devi.U
