I run 2 completely different servers on my boxes and it has served me well with the old trusty f5's over the years. One server scrambles the other kicks in..! Ive been noticing on the zgemma.. Im getting a bit of freezing over the weekend and Im putting it down to the 2nd server kicking in? The f5 in kitchen is fine with exact same servers. Ive emailed both guys just in case its something to do with a dual tuner sub but is there anything else tk's can think of? Is the zgemma possibly more unresponsive when changing the server over?
