Cannot delete virtual server because of sflow

Hey all, I have a lab setup with two LTMs in HA, and was trying to clear out some configs, when the standby suddenly refused to sync properly. When I examined the standby system's logs, I saw the ...

    can you try this?

    on active
 tmsh modify cm device-group (device group name) devices modify { (active device name) { set-sync-leader } }
 tmsh run /cm config-sync to-group (device group name)

on standby
 touch /service/mcpd/forceload
 reboot

Hi,

I recently faced the same issue. But I was under the impression it resulted from a modified default http profile.

To resolve the problem I manually deleted the modified http profile from /config/bigip.conf and reloaded the configuration from config files after stopping the mcpd, deleting the binary config files and restarting the mcpd on the affected unit. 
bigstart stop mcpd
rm /var/db/mcpdb.*
bigstart start mcpd
tmsh load sys config

Now config save and config sync worked properly. Instead of modifying the default http profile, a new profile (defaults from http) was created with the required standard settings to be used now as master template for new http profiles. Please be careful when applying the steps above. If in doubt, open a case with F5 support.

Thanks,

Stephan

PS: Modifying the default profiles always seemed to be a bad idea. But in case of analytics profile it´s actually required i.e. to track client subnets.
