ltm nodes down ICMP monitor fail, but ping from TMSH get success!

Hi,

I open a case at F5 support and I need to do upgrade.

There are similar bugs to my problem which has a temporary workaround. 2 most popular problems related to this error message:

In my case the problem is similar to bug:

Bug ID 620079: Removing route-domain may cause monitors to fail.

Workaround describe for this bug, is working in my case:

bigstart restart bigd

ICMP starts work - and we do not have any impact on traffic process. This only restarts process responsible for monitoring.
