Hi All ,

As Ops team informed that the server is showing status_unknown in candle.
Hence tried to stop and start the candle agent.

I am getting this error while starting candle agent , after stopping candle agent.
# cd /sbin/init.d
# candle start

...
..
(4417A108.2B0C4F38-1:kuxmain.c,298,"kuxmain") kuxagent process group set.
init_sock: Failure to open /dev/kmem, errno = 13: permission denied
(4417A108.2B7CD7D0-1:kux00agt.c,100,"TakeOffline") No heartbeat available to take offline.
uxdc **** kuxagent terminated ****

---------------
Server: N4000 , hp-ux B.11.00

Does anyone have any idea ,as whats problem.

Thanks.

Hi rveri,

UNIX error 13 means Permission Denied. Check the permissions of /dev/kmem

Hi Muthukumar and Indira , thank u for quick replies..

The permission is :

# ls -l /dev/kmem
crw-r----- 1 bin sys 3 0x000001 Jan 21 2000 /dev/kmem

root@server1
# file /dev/kmem
/dev/kmem: character special (3/1)

----------------------------------------------------------------------

It seems no problem with the permission as I compared with another server running candle , and seems no difference in the file.

Here # ps -ef | grep candle only shows only one agent is running : i.e kulagent (Unix Log monitoring Agent). The other agent kuxagent (Unix OS Monitoring agent) , is not runnig. And restarting of candle is giving the above error of /dev/kmem.

Any idea, whats wrong.

Thanks,

What is the user, group and permission information for kuxagent binary. Compare with running process binary.

Hello,

I think, "cadle" is used to collect datas from host using SNMP request. Which user trying to execute the command to start ?

Hi,

See if there are any IPCs left behind from the previous run. Those could be causing problems too.

ipcs -a | grep -i

cheers!

Hi ,

You can also check the permission for kuxagent , under /opt/candle/hp116/ux/bin/
