The article referenced only applies to Avamar 4.x. The crons are no longer used in Avamar 5.x or higher.
The message means that some data is being swapped out of memory and onto disk by the Linux kernel running on the storage nodes. In Avamar 5.x and 6.x, a certain amount of swapping is normal and nothing to worry about.
If one particular node is reporting a lot of swapping, there may be a DIMM failure on that node. The output of the following command (run as the admin user with the SSH keys loaded) will tell you how much memory is available to the OS on each node. Take a look at the 'total' column.
mapall --noerror 'free'
Here is some example output from a Gen2 2TB node system:
I would not recommend disabling this message -- if one node reports the error over and over, it could be a symptom of a bigger problem such as a memory failure.
A change that should reduce the number of swapping messages reported by the nodes will be included in Avamar 6.0.2 and Avamar 6.1.

Hi Petter,
Please check the following Powerlink article about that warning message:

Hope this helps you.
Thanks,

Hi again,
That dosn't seem to help, from what I can find 'morning_cron_run' is located in /usr/local/avamar/bin/ and only on the utility node;
root@avamar:~/#: find /usr -name morning_cron_run -print
/usr/local/avamar/bin/morning_cron_run
And the gccount=64 flag is not set in that file or in the hfscheck_cron script... did I miss anything?
#!/bin/bash
echo 'morning_cron_run starting: '
date
ssh-add ~dpn/.ssh/dpnid
cd ~dpn
mccli mcs waitforflushcomplete
sleep 300
gc_cron
sleep 3600
cp_cron
sleep 300
hfscheck_cron --throttlelevel=1 --useschedule
sleep 300
cp_cron
health_check.pl > /usr/local/avamar/var/cron/health_check.log
echo 'morning_cron_run ending: '
date

This particular system has 16GB of memory on each node.
If one node is reporting less memory than the others, please contact support for assistance in resolving that issue.

Is there a way to disable the check for "server node %s is swapping"? Or isn't that recomended?
Regards,
Petter
