Hi All,

We have recently migrated postgres DB to out of of server ( Centos 6.9 ) .
Both Source and Target versions of OS/DB are same . Also Configuration is Apple-Apple.

But We started seeing lot of process name 'migration' at OS Level in new server which is triggering Load average most of the time  .

Some sample process from top command,

    67 root      RT   0     0    0    0 R 34.8  0.0 913:06.38 [migration/16]                                                                         
   155 root      RT   0     0    0    0 S 32.2  0.0 845:46.53 [migration/38]                                                                        
    35 root      RT   0     0    0    0 S 27.6  0.0 927:15.27 [migration/8]                                                                           
    11 root      RT   0     0    0    0 S 21.4  0.0   1033:45 [migration/2]                                                                            
   131 root      RT   0     0    0    0 S 21.4  0.0 812:00.70 [migration/32]                                                                        
    87 root      RT   0     0    0    0 S 20.7  0.0 394:28.32 [migration/21]  

Anyone come-across this situation ? Please share your thoughts .

I googled "linux root migration" and found this:
https://serverfault.com/questions/674685/kernel-processes-periodically-eating-cpu-during-high-load

It has some pretty good answers.
