I am getting the exact same thing using Logic X 10.0.5. Master is Mavericks 3.46Ghz 6 core Xeon Mac Pro with 24Gb of ram 256Gb SSD for system drive and 750Gb WD Black for samples drive. Slave is Windows 7 Ultimate Dell T7500 with dual X5560 2.8Ghz Xeon's 24Gb system drive is 150Gb WD Velociraptor and 300Gb WD Velociraptor sample drive. I think I have narrowed it down to my network cards. Computers are direct connected with CAT 6... Dell has a cheap Realtek Gigabit card and the Mac no longer supports jumbo frames after upgrading to Mavericks. This setup worked fine before so I am assuming its the loss of jumbo frames... am I correct in this?. I just ordered 2 brand new Sonnet Presto PICe Gigabit cards that will arrive Monday and can report back then. Thanks!

Thanks for that. I really am a complete idiot when it comes to computing - I had no idea about jumbo packets. So I checked the settings of my LAN adaptors, and discovered that jumbo packets were disabled on both machines. I've enabled them and the audio outs seem to have immediately improved dramatically. They're not gone altogether, but I now seem to get one every few minutes, whereas I was getting several every minute before. Any further suggestions would be welcome, as I still hope to eliminate the problem. I've checked the connection diagnostic in device manager, and both machines claim to be running fine at 1Gb.

Thanks again DRC Music,
As it happens, I was just having a lucky few minutes last night. Tried it this afternoon, and things were worse than before, even with the largest jumbo frames enabled. But then I decided to connect the computers directly to each other, and I've had a couple of hours where I haven't been able to make the slave machine glitch once. So the solution is probably a new switch. Annoying, since the one I have claims to support jumbo frames, but at least it's not the biggest expense in the world.

Turns out I'd been even more bone-headed than not knowing about jumbo frames. My static ip addresses simply hadn't stuck, and I didn't realise. The first thing I did was go and assign addresses, so I assumed that was sorted. But today I started getting just occasional glitches even with a direct connection between machines; so in desperation I completely retraced all my steps. When I went into the ip4 properties, it turned out that DHCP was turned off, and the 'use this address' option was selected, but the box for the number was blank - on both machines.I tried putting it back in, but every time I left the properties window and came back, it was gone again. I have no idea how the machines were even talking to each other, but it must have confused the heck out of my switch.
The only thing I could think was that I had attempted to assign the machines the same IP addresses that they had been dynamically assigned at the moment I set them up; perhaps each machine saw itself as a potential clash, and refused to take the address. So I assigned new addresses, which stuck, and haven't had a single glitch since. Even my swtich turned out to be fine -so happy days.
