System Check error : Actual open files limit:7000, needed 8000 nodes:

Hi,

System check showing up error 'Actual open files limit:7000, needed 8000 nodes:' in our BIA system.

SAP BIA Admin guide suggested open files limit should not be less than 8000. I verified at OS level

ulimit for open files (-n) is displayed as '8000' which is good.

Please suggest me how to fix this error. What if we increase ulimit value for open files at OS level?

Thanks in advance

Regards,

Srinivas.
