First, in the 8.2 family this bug is fixed in 8.2.4 and later so updating ONTAP is the best option. If that isn't possible the next best thing is to monitor.
I created a collection template and grafana dashboard to visualize it like this:
This metric is the send lock-create total operations as mentioned in the bug. If the number is >1.5 million you should do a proactive reboot.
To set this up see the zip file here:
These files are to visualize bug id 901008 (http://mysupport.netapp.com/NOW/cgi-bin/bol?Type=Detail&Display=901008)
ATTN: You must use NetApp Harvest v1.3 or later!
1) Copy the conf file to /opt/netapp-harvest/template
2) Add collection of a new template to capture the additional counter needed by editing your netapp-harvest.conf poller entry for
the cluster where you want to enable the extra counter by setting:
template = bug-id-901088.conf,default
So an entry which includes these counters might look like:
hostname = 192.168.22.2
group = AMS
template = default,bug-id-901088.conf
3) Restart the poller /opt/netapp-harvest/netapp-manager -restart
4) In the Grafana GUI choose the dashboard list and then import. Select the json file and load it. Within a few minutes
you should see metrics arriving.
Let me know how this works for you!

You are amazing!
I can predict when to panic reboot, Because you helped me.
It will take time to Upgrade cDOT8.2.4 or later.
Before 1.5 million, to cDOT8.2.4 or later planninng.
