Maybe... but all the servers have the same configuration either software or hardware. today morning it also happend. and i shut down the server then unplugged the power cables then waited for 3 minutes. then powered it on back. the system started wor a while OS worked slowly i decided to shutdown again. but in 3-5 minutes OS bocome workable and there was no reason to shutdown the server. But is was only once. In another situations i do shutdown and unplugg the power cables two times.
these are thoeries only. how i can test it by myself?
