DM RELOAD will it impact my Data Center Traffic?

Oh Wise and Mighty Collective. (Ok..that might be a bit of a dorky intro )

We are seeing a discrepency between what the Device Manager (GUI) indicates about Normalization on a particular context and what the CLI has been programmed. We have turned Normalization off due to an issue with the applications that are served by this contect. The DM (GUI) indicates that it is turned on. Cisco Tac has indicated (I always appreciate Cisco Tac!) that we should reload the DM with the DM Reload command. I have found in a couple documents an entry that indicates that the DM Reload command is not impactful. It would also seem logical to me that this service wouldn't be impactful to be restarted. However, I want to do my due dilligence and ask the collective what their experience has been.

We are experiencing a strange issue with the servers being served by this context. It just materialized and it might have something to do with a TCP Port Reuse issue. The system just had a OS upgrade. So I believe the two might be related. I want to eliminate any discrepencies with the ACE before continuing troubleshooting.

Here is one of the documents that indicated a DM Reload is not impactful.

Hi Wilfred,

Dont worry about DM reload, that command will reload only the DM process, does not affect the loadbalance, routed or any traffic that is passing the ACE

Hi Wil,

DM reload should not affect or impact your production's environment. DM reload just reset all the Java processes related to the GUI itself but it does not impact any load balancing processes or anything like that.
