Greetings,
The question pertains to a two node RAC cluster running Oracle
10.2.0.3.0 SE on 32-bit Linux 2.6.9-67.ELsmp. CRS, ASM & RDBMS are each
in a separate home. Yesterday on node 1 I started seeing messages in the
/var/log/messages file of the form...
Mar 20 07:5:34 spenser init: Id "h3" respawning too fast: disabled for 5
minutes
We did some looking around to try and determine the cause of this but
didn't come up with anything immediately. There were a core dump
generated in the $CRS_HOME/log/<node_name>/crsd directory at about the
time we noticed this beginning. Various error messages indicating
various failures (I can provide a segment) appeared at this time in the
crsd.log also. At this point I didn't know what was occurring so opened
an SR with Oracle.
This morning, which gathering some additional information I found that
on node2 in this cluster there were a large number of racgmain processes
running and the number of these processes running was increasing, all
the swap space and virtually all of the memory on this node were in use.
Some of the processes were running out of the CRS home and some out of
the ASM home. I did some investigating to see if it would be possible to
stop these processes gracefully and was unable to gather any
information. Ultimately we rebooted node2 of the cluster and everything
appears to be functioning as is expected at this point.
My question is what would cause the racgmain process to run amok this
way. Currently ps -ef|grep racgmain shows none running on either node.
I'm puzzled by this and other than information indicating that this
process is part of ONS I am not able to find any further information or
details. Any suggestions would be greatly appreciated.
Thanks.
