InvalidOperationException - HELP!

I have a SOAP interface which makes calls to the F5 to get data about stats, pools, members, etc. You ask, why write another web service that talks to the F5. Simply because I have simplified a lot ...

Did you guys ever get an answer to this issue? I'm (we're) building a similiar tool and seeing similiar errors -- very low frequency (0-15 times/hr) on VERY static iControl calls to test-only lab devices. Is this a call contention issue -- one call (to save config) ties up the iControl portal until other iControl calls timeout?

 

 

Thanks,
