Hello Jaechul,
Coredumps have to be analysed by TAC.
If it is Kernel oops then it definetly need to go for more analysis to engineering.
i would recommend you to open a case with TAC.
collect "show tech all"
show log messages nvram
upload debug ---for coredump.
show debug system-dump ---will show core dumps if any

As it has happened in 15.4 I would request you to do this so
that Extreme can fix this for more stability.
