No buffer space available

[PROSANJIT MALLICK]

Hi all,

Yesterday all my users where unable to ping my server.
while self-pinging my server I got an error No buffer space available. As a result I had to restart my server.

Is there any other way to solve this problem

Any help in this regard will be highly appreciated.

Regards
Prosanjit

Hi Prosanjit:

You don't specify the OS (10.20, 11.0 ?).

For 10.20 there is a 'ping' patch: PHNE_19566. For 11.0 see PHNE_16158. I would definitely get one of these from the Patch Database and install it if you haven't already.

I'd also make sure you have current ARPA networking patches.

You can set dynamic buffer space allocation on your server. From kernel configuration menu, set nbuf and bufpages to zero(0) and swapmem_on=1.

Use "echo bufpages/D | adb -k /stand/vmunix /dev/kmem" command to see the current buffer size of use sysdef before making the modifications.

With this information, modify the dbc_max_pct and dbc_min_pct values in your kernel.
