Hi Azat,
Are there known usages of libevent within Android applications ?
In my experience JNIs are really tricky to debug for memory corruption and given the event driven nature, doubly confusing.
Is there an official jni for libevent. I'm wondering whether that would be a good direction to explore for Vijay, else consider evaluating jzmq for his use case, if design of the remote side is still work in progress.
Thanks Azat, I will try and see if I can make work with [1[ or [2]. But this issue happens sometime only and we have no specific test case to reproduce this issue 100%. If finding the root cause becomes very hard, Can we try to add some "protective code" to avoid such crash ?ÂÂThanks and RegardsVijayOn Fri, Apr 8, 2016 at 5:54 PM, Azat Khuzhin <a3at.mail@xxxxxxxxx> wrote:On Fri, Apr 08, 2016 at 05:41:04PM +0530, vijay mishra wrote:

Well it is not easy to answer this question, since if application mess
up with memory somewhere then you definitely can have such
problems/crashes.
And valgrind will show this mess (invalid read/invalid write).
You don't need to recompile the whole program to run it under valgrind,
all you need is to compile valgrind, and you can take a look here for
the help [1].
Also you can try newer version of libevent [2].
If you can't do [1] or [2], then it will be *very hard* to find the root
cause of the problem, but of course you can use libevent internal
debugging facilities:
 event_enable_debug_mode();
 // event_enable_debug_logging(EVENT_DBG_ALL); // and try to analyze logs after this
