after i login the system, it always returns "fork failed" whatever i typed in. so I had to restart the system.
I found some messages in OLDsyslog.log that I pasted below:
----------------------------------------------
Mar 20 23:28:56 cs_svr03 vmunix: kthread: table is full
Mar 20 23:29:40 cs_svr03 inetd[915]: ftp/tcp: accept: Bad file number
Mar 20 23:31:22 cs_svr03 vmunix: kthread: ta...
Mar 20 10:37:02 cs_svr03 ACEAGENT: Failed to create Thread.
-----------------------------------------------
I guess the reason may be related to system resource limits. but I don't know which parameter should I tune? could you give me a hand?
sincerely yours
Andy.

Re: vmunix: kthread: table is full
I've seen the problem. nkthread's value is 9458. it's even less than default value 17971 (((NPROC*7)/4)+16). the nproc is 10260.
Now I plan to reconfigure the kernel. Would you please have a look at the steps I wanna follow and correct it?
step 1: cd /stand; cp system system.prev
step 2: select "Process New Kernel" from the SAM action menu.
step 3: select "Move kernel into place"
step 4: select "Shutdown/Reboot System Now"
thanks!

Re: vmunix: kthread: table is full
The steps are ok except:
step 1: cd /stand; cp system system.prev
i would also copy vmunix
e.g. cp vmunix vmunix.prev
just to be cautious...
kind regards

Re: vmunix: kthread: table is full
To Reconfigure kernel, you can follow these steps,
1) Copy /stand/system & /stand/vmunix
2) /stand/dlkm
3) Use SAM to reconfigure and build kernel
4) Reboot using new kernel.

Refer mike tully's reply. It is telling all about kernel rebuild after parameter change.
