  • EMS logs also showed repeated mgwd process memory exhaustion and allocation failures.

[kern_mgwd:info] ERR: tz_mgmt: timezone error: magic_load() failed: Cannot allocate memory: cannot map `/usr/share/misc/magic.mgc` (Cannot allocate memory)
[Node01:mgwd:kern.vm.mmap.return:notice]: mmap(2) by mgwd(pid5373) for size X failed: VMEM limit exceeded, limit 4294967296, error 12.
