[Draenor] Memory leak

[Morketh]

Blasted lands is phasing rapidly between phases
I then picked up "The Dark Portal" and then went back to the blasted lands....
phase is now locked but Khadgar is not there....
I then set the quest complete via GM commands to see if it was just a missing the NPC nothing changed so i teleported to Frostwall (on bloodelf hunter) i managed to gm quest complete a couple quests to get a garrison but the next toon i took to the area a garrison was already built and unobtainable. walking in and out of the garrison had the proper name tag on it saying it was my outpost but adding a garrison hearth stone via gm commands the system told me i dont own a garrison on my second toon
at this point my first toon started spazzing out and repeating the Swift Hand of Justice animation (Heirloom trinket) rapidly
i had to alt+f4 the game client and was unable to log back in

i left the realm running over night and the Linux kernel killed the worldserver sometime over the night
Image is from Monitorix system has 56Gb of RAM

also system load during that time period spiked and the system become unusable

Swap space was also maxed out during the time in question
