sunrpc.tcp_slot_table_entries is not persistent over reboot in sysctl in RHEL 4 and 5

Solution Verified - Updated -


  • NFS sunrpc module allows one to specify sunrpc.tcp_slot_table_entries parameter.

  • This parameter can be put in /etc/sysctl.conf.

  • Putting a value of say 64 and rebooting the machine causes the value of this parameter as observed by sysctl -a | grep sunrpc to show up as 16.

  • When setting it up manually with sysctl -w sunrpc.. it works fine but if put in sysctl.conf it doesn't.
