IC85631: ONPLOAD'S FD RLIM_CUR EXCEED 256. FD VIOLATION CAUGHT BY OPERATING SYSTEM.

APAR status

• Closed as program error.

Error description

• This is an enhancement request to increase the FD rlimit for
  onpload above 256. This value is set in the main. We put fd's
  rls.rlim_max of 256, however, this value is no longer valid. The
  following warning is observed in /var/adm/message. As the
  system's hard limit for nofiles were set to 'ulimited', hpl
  loaders were able to run without failure. However, continual
  dump of below message concerns customer as they are filling up
  their system log every time onpload runs.

  /etc/rctladm.conf or set it to =none
