正如在这个问题中已经回答的：JVM_FindSignal函数连续分配本地内存
jemalloc报告JVM_FindSignal的泄漏与缺少调试符号有关。我当然安装了调试符号，请参阅：

仍然我的jeprof输出如下：

还有什么需要考虑的吗？
事实证明
openjdk-8-dbg软件包将带有调试符号的文件安装到/usr/lib/debug/.build-id中jeprof在/usr/lib/debug/{FULL_SO_PATH}中查找调试符号
因此，这是jeprof中不解析.note.gnu.build-id部分的错误和dbg包不包括调试库的完整路径符号链接的问题的组合。
要解决此问题，您可以手动创建相应的符号链接：
ln -s /usr/lib/debug/.build-id/16/240e0172c3fc0dd6e974325c8ad1d93723ccac.debug /usr/lib/debug/usr/lib/jvm/java-8-openjdk-amd64/jre/lib/amd64/server/libjvm.so
(文件名取自gdb输出(
然而，即使jeprof能够读取调试符号，这在Java应用程序的情况下通常也没有帮助。问题是jemalloc不知道如何展开Java堆栈。有关示例，请参阅此演示文稿。
考虑尝试异步探查器，它可以显示混合的Java+本机堆栈。使用异步探查器分析malloc、mprotect和mmap调用有助于发现Java应用程序中的本机内存泄漏。有关详细信息，请参阅此答案。
这里有一个jeprof的补丁，它可以更智能地查找调试符号。这是基于@apaingin的回答。
