Memory leak after send_v2trap() method

Hi All,
I am using JNI, I am calling JNI interface from Java so that I can use
native code . While doing so I am facing a memory leak which after doing
like this Please find the pseudo code .

JNIEXPORT void JNICALL
__nativeSendTrap
                        (JNIEnv *pEnv,
                         jclass clazz,
                         jlong es,
                         jlong cid,
                         jint es,
                         jint en,
                         jint Sev,

I suspect the snmp_free_varbind(_EvtNotification_vars); is not realeasing
the memory please do suggest me something
