Question by Ted F. · Oct 29, 2013 at 12:24 AM ·

Do Automatically triggered Mem Dumps on OOM force a GC first?

I had this question raised by a customer and wanted to get the correct info.  When a Mem Dump is automatically triggered by the 1.6 or greater JVM OOM is a GC triggered first?

thanks,
ted

hi,

yes, by default an OOM triggered dump runs a GC first.

You can change this with a collector system-property: -Dcom.dynatrace.memdump.gcOnOOM=false

best, manfred
