System Console "kthread table full" or "fork failed"
Messages
After a successful cold install, the system starts displaying console
messages such as kthread table full or fork failed console. These
messages are also logged in /var/adm/syslog.log.
This is caused by the maxusers kernel tunable not set at high enough
value.
How Do You Know
if This Affects You
An example of what you might see is the following message logged onto
the system console:
kthread: table is full
You would also see the following message being logged in
/var/adm/syslog.log:

The above example demonstrates table is full messages; however, you
might see the similar “fork failed” messages.
What To Do To correct this, increase the maxusers tunable to 200:
Step 1. Log on as root
Step 2. Edit /stand/system and add maxusers 200
Step 3. Run the following commands:
mk_kernel -v -o /stand/vmunix
kmupdate
reboot -r
