<div>looks like it is problematic to use LD_PRELOAD i had various crashes. I understand it is too much to ask, any configuration to look out for? </div>
<div>I think most probably i will use JNI to load jemalloc (<span class="Apple-style-span" style="font-family: monospace; font-size: 12px; white-space: pre; ">LD_LIBRARY_PATH</span>), looks like that works fine so far.</div>

I really don't know anything about how the JVM is structured internally , how it interacts with malloc, how it uses/abuses dlopen(), etc., so I'm not going to be of much help without a lot more background information.</div><div><br></div><div>Thanks,</div><div>Jason</div></body></html>
