** [tickets:#2470] imm: IMMND coredump when discarding client**
**Status:** accepted
**Milestone:** 5.17.06
**Created:** Mon May 29, 2017 04:05 AM UTC by Hung Nguyen
**Last Updated:** Mon May 29, 2017 04:05 AM UTC
**Owner:** Hung Nguyen
**mLastResult** of **ImmSearchOp** was double freed in
**immnd_evt_proc_search_next()** and later in
**immnd_proc_imma_discard_connection()**.
In **immnd_evt_proc_search_next()**, before jumping to **agent_rsp**,
**mLastResult** must be cleared. So that it will not be freed again in
**immnd_proc_imma_discard_connection()**.
