thanks a lot for the pointer..We actually had the issue of MICs overheating..we have added air duct in the server and then we could see that there is temperature decrease of 10 degrees. Also noise is reduced by 25 dB. However as no work is done by MICs, they are just idle, then also why temperature should increase?
Also we fail to understand, our servers give kernel panic and returns to a # prompt wherein only /dev file system is mounted.
