NFS kernel parameter

Hello everyone,

 

I have a question/problem about the kernel parameter :
sunrpc.tcp_slot_table_entries

 

We are running SAP on Linux (SLES9 SP3), the DB storage is located on a
NetApp filer connected via NFS. 

 

To improve the NFS performance I want to increase the mentioned
parameter to 128. But after activating this parameter the systems hangs
totally when I want to start the database. I have done some checks, and
the maximum value I can use is 32.

The default for this parameter 16.

 

Is there someone who has the same problem or can give advise to solve
this.

 

Best regards,

 

Gert van Zuylen
