ftds.NewConnPool does not return, once in a long while

[abkhan]

Last few months, two times we have seen in a live system that after some network event, ftds.NewConnPool does not return. I was expecting that if it could not connect, it would return within some time, but somehow it just does not.

I still can not determine the cause of this happening but could at least see from logs this symptom - as this is a prod system.
