Hiya folks, I am hoping to use Valgrind to help me figure out where some mysterious native memory leaks are happening with a server program I have written in Java. I have found, however, that Valgrind seems to be exiting prematurely. I wrote a simple test program that simply loops and outputs to the console for 10 seconds, and even with that, Valgrind ends immediately. Here is my command to run it with Valgrind:
valgrind --trace-children=yes java NewClass And the following is the output. Any help or insight would be greatly appreciated! -Jess ==36360== Memcheck, a memory error detector ==36360== Copyright (C) 2002-2017, and GNU GPL'd, by Julian Seward et al. ==36360== Using

Note: see also the FAQ in the source distribution. It contains workarounds to several common problems. In particular, if Valgrind aborted or crashed after identifying problems in your program, there's a good chance that fixing those problems will prevent Valgrind aborting or crashing, especially if it happened in m_mallocfree.c. If that doesn't help, please report this bug to: www.valgrind.org In the bug report, send all the above text, the valgrind version, and what OS and version you are using.
