Is it possible to avoid using a specific port? The port may be<br>
already in use for a thousand of reasons, and this will break the test.</div></div></div></div></blockquote>Done, the aim here was to make one port busy to make sure, that no other tarantool instance use it.<br>But here was an error due to this port was socket based.<br> Update this code and transfer found port to replica script as a third parameter.<br><blockquote style="border-left:1px solid #0857A6; margin:10px; padding:0 0 0 10px;"><div id=""><div class="js-helper js-readmsg-msg"><div><div id="style_15230045960000000958_BODY">

Why? What's magical about this number? Could you use 100 * 1024 *<br>
1024 instead? Then it's clear the test is not using too much<br>
memory and the exact amount is also clearly visible.</div></div></div></div></blockquote>OK, it was "copy exactly" principle, just reuse same value.<br><blockquote style="border-left:1px solid #0857A6; margin:10px; padding:0 0 0 10px;"><div id=""><div class="js-helper js-readmsg-msg"><div><div id="style_15230045960000000958_BODY">
