Would you be able to enable KDDR logs and Netdump logs to be collected the next time you see a system core dump? KDDR logs can be found in the ExtremeCloud IQ instance by clicking on the silhouette icon in the top right corner>Global settings>Logs>KDDR. Netdumps can be set up in Manage>Check box next to host name>Actions>Advanced>Update netdump settings. If you could send those logs to me at communityhelp@aerohive.com, I will get them reviewed and let you know what we find.
