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:
