It should have been included by default in the incidents like "Application Process Out-of-memory". Check it. If you are not sure, just check the logs which incidents are triggering Dumps. Easy !
We have a lot of servers which are dynatrace agent enabled.If it is because of default incindent, other servers also should had this problem. But just one server is creating the crash dump files. I think it is related with the agent settings in system profile but could not find.
It should be in your Incidents. Look up for which incident it is triggering (if you do not know open each Incident and click on Actions-->advanced options and then you should see "Memory Dump Action Plugin" in the list). Remove it from actions list.
Maybe a little late, but we had this issue too once and these dumps have nothing to do with memory dumps, but are native crash dumps.
Which ideally should be resolved by finding a root cause. But you can also disable them using the debugSuppressCrashDumpNative debug flag. Setting debug flags on an agent is described here: https://community.dynatrace.com/community/display/DTKB/Setting+AppMon+Agent+Debug+Flags
