CR ID Description
6303418 M9000 server with a single domain and 11 or
more fully populated system boards might
hang under heavy stress.

single NIC card with more than 5,000
connections.
6441349 I/O error can hang the system.

corruption could occur due to a race condition.
The window of opportunity for this race
condition is very small.

load after uncorrectable error(UE) panic.
Systems will function correctly but events
normally automatically diagnosed by FMA
using this module will require manual
diagnosis.

Workaround
Do not exceed 170 CPU threads.
Limit the number of CPU threads to one per
CPU core by using the Solaris psradm
command to disable the excess CPU threads.
For example, disable all odd-numbered CPU
threads.
Use multiple NIC cards to split network
connections.
There is no workaround.
There is no workaround.
If the problem has already occurred, use this
workaround:
1. Remove the cpumemdiagnosis file:
# rm /var/fm/fmd/ckpt/ \
cpumemdiagnosis/cpumem -diagnosis
2. Restart fmd service:
# svcadm restart fmd
To avoid this problem in advance, add "rm -f
/var/fm/fmd/ckpt/cpumemdiagnosis/
cpumem-diagnosis" in the
/lib/svc/method/svc-dumpadm file as
below.
#
savedev=none
rm -f /var/fm/fmd/ckpt/cpumemdiagnosis/
cpumem-diagnosis
