How do I stop .mdmp files from being created

Question

I have an instance of Solr, hosted with Tomcat that recently started creating minidump files. There are no errors in any of logs, and Solr continues to work with out a hitch.

Answer 1

Generally speaking when JVM crashes the content of hs_err error log file (controlled by -XX:ErrorFile) is often enough to point what the trouble may be.

To prevent Oracle JVM Hotspot to generate Windows minidump (mdmp files), the JVM option to use on command line is: -XX:-CreateMinidumpOnCrash

It exists since 2011 but was very difficult to find: How to disable minidump (mdmp) files generation with Java Hotspot JVM on Windows
