Hi all,
I have 3 2-node clusters, running just cluster suite,
without gfs, each one updated with the latest
packages released by RHN.
In each cluster one of the two nodes has a
steadily growing system CPU usage, which seems
to be consumed by clurgmgrd and
dlm_recvd.
As an example here is the running time accumulated on one
cluster since 20 december when
oit was rebooted:
[root@estestest ~]# ps axo
pid,start,time,args
PID STARTED TIME
COMMAND
...
10221 Dec 20 10:37:05
clurgmgrd
11169 Dec 20 06:48:24
[dlm_recvd]
...
...
[root@frascati ~]# ps axo
pid,start,time,args
PID STARTED TIME
COMMAND
...
6226 Dec 20 00:04:17
clurgmgrd
8249 Dec 20 00:00:19 [dlm_recvd]
8249 Dec 20 00:00:19 [dlm_recvd]
...
I attach two graphs made with RRD which show
that the system CPU usage is steadily growing:
note how the trend changed after the reboot on
20 december.
Of course as the system usage increases so does
the system load and I am afraid of what will
happen after 1-2 months of
uptime...
Does anybody else see this behaviour? Any hint
on a solution?
TIA,
Marco Lusini
