<p class="MsoNormal">Hi All<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">My application worked perfectly with LD_PRELOAD and the virtual memory growth was contained. As soon as I linked it dynamically with jemalloc, this wasn’t the case. So virtual memory kept growing. So I am guessing that my application is
still not using jemalloc but libc’s default malloc when linking dynamically. My application is a binary which links to many dynamically loadable libraries some of which are internally built and some are open source versions which we don’t always build. My
questions are:-<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoListParagraph" style="text-indent:-.25in;mso-list:l0 level1 lfo1"><![if !supportLists]><span style="mso-list:Ignore">1.<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]>When linking dynamically with jemalloc, is it a requirement to have –ljemalloc as early as possible or possibly the first library being linked to, to override the default malloc ?<o:p></o:p></p>
<p class="MsoListParagraph" style="text-indent:-.25in;mso-list:l0 level1 lfo1"><![if !supportLists]><span style="mso-list:Ignore">2.<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]>What method does jemalloc uses while linking to override malloc, does it use the malloc_hooks to override or just the normal linking, so that whatever the linker gets first, it will link to .<o:p></o:p></p>
<p class="MsoListParagraph" style="text-indent:-.25in;mso-list:l0 level1 lfo1"><![if !supportLists]><span style="mso-list:Ignore">3.<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]>Would linking statically solve this issue, although my preference would be to link dynamically since I have at least 10 processes which needs jemalloc, and at least they would share the code in memory.<o:p></o:p></p>
<p class="MsoListParagraph" style="text-indent:-.25in;mso-list:l0 level1 lfo1"><![if !supportLists]><span style="mso-list:Ignore">4.<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]>When linking with external open source libraries, do I need to re-compile those with jemalloc as well to make sure any mallocs in those libraries also go through jemalloc or that is not required. I am guessing it should not be required
as long as my process links to the right malloc library, their dependencies should be correctly resolved.<o:p></o:p></p>
