Re: Buffer space
This is a problem with one of the service guard processes.
see that /etc/services is correct and the settings in inetd.conf are correct. Some modifications are required to make 11.16 SG work properly.

Re: Buffer space
a) If your cluster is still fully operational,
check the usage of the server at the time when
maybe transient error was logged.
b) I hope your are running ServiceGuard
11.17 or above. This error was known to
happen on SG 11.16.
c) How old are your patches?
Set up Software Assistant and do the audit.
It takes five minutes to do it.
For example, patch PHSS_37608 deals with
some of buffer problems in SG 11.16.
d) Otherwise, check kernel usage. For
example:
# echo "bufpages/D" | adb -o /stand/vmunix /dev/kmem
# sysdef |grep bufpages
You might modify the dbc_max_pct and dbc_min_pct values in your kernel if
their values are not correct.
Cheers,
