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,
jint eTime,
jstring rP,
jstring fO,
jint ek,
jstring fT,
jbyteArray eP,
jint aP,
jstring sT,
jstring trapOID)

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