glibc detected error

Rcky Mntere — Wed, 02 May 2007 16:24:55 GMT

After installing an openview agent (sucess) and starting the agent via opcagt -start we are seeing multiple instances of the processes:

Any suggestions for troubleshooting this?

latest patches for the ovo agent installed?
there is nothing you can do about this, it is a protection build in to linux.

meaning, there is a programming mistake in the opcagt command that needs to be fixed (but afaik this was solved in an HP patch).

I suggest you to stop you both ovpa and opc

/opt/perf/bin/ovpa stop
/opt/OV/bin/OpC/opcagt -stop

ps -ef|grep -i opc
ps -ef|grep -i perf
and make sure no processes left running

start as fresh.

If it still errors out, check /var/opt/perf/stattus* file for each failed process

if the gilbc error repeats check the glibc veriosn you have (i386 aginst i686); whihc RHEL/kernel veriosn you have.
