Hello All,
In one of our production system, Paging usage is high eventhough physical free ram is available.
We have checked and found that we are not getting any memory dump (like PXA_NO_FREE_SPACE) in the
system.
But we found paging usage is more eventhough there is no activity happened in the system and more physical RAM is avaliable
AIX team confirmed that everything is fine from their end.
Could you please let us know whether we can set rdisp/wp_auto_restart to 86400 S. Also let us know if there is any drawback / dependency need to be checked by setting this parameter.
Also please confirm if there is any paging parameter need to be reduced to resolve this issue
