<div dir="ltr"><div>Hi, <br></div><div>I am not sure if this is the right place to post
this issue. We are testing out ZGC in a Xmx975G JVM. It crashed with
the attached hs_err file. <br></div><div><br></div><div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"># Internal Error (zMarkStackAllocator.cpp:81), pid=34334, tid=38183<br># fatal error: Mark stack space exhausted. Use -XX:ZMarkStackSpaceLimit=<size> to increase the maximum number of bytes allocated for mark stacks. Current limit is 8192M.</blockquote><br></div><div>How can I find the right size for ZMarkStackSpaceLimit, so that jvm does not crash?</div><div><br></div><div>Can
ZGC handle this case in a more graceful way ? Can ZGC
adjust ZMarkStackSpaceLimit dynamically ? I mean, in a production
environment, we cannot keep crashing JVM until we find the right
ZMarkStackSpaceLimit value. <br></div><div><br></div><div>thanks,</div><div>Abdulhakim Unlu</div></div>
