Feed freezes

I've got a problem with my CNC / Mach freezing, and can't find any posts for this exact problem:

 I have been running some longer programs (89,000+ lines...), and at random times, the mill will freeze in place. Mach stays frozen on one line in the display, but the PC isn't frozen. I can click on various buttons on Mach. Clicking on 'Cycle Start' has no affect, but clicking 'Hold' turns the highlight off on "Cycle Start". If I hit "Cycle Start" after "Hold", it will not light up again. If I hit "Stop", it stops as it should. I hit "Cycle Start" one time, after I had hit "Stop", and it did start up again, but as the spindle had stopped, it promptly broke my carbide endmill (oh joy... ). This has happened 3 times on the same program, but at different points. I have restarted the computer after each incident, as well as the Galil card. I saw in another post that someone had issues with having a flash drive plugged in ( that's how I transfer my files to the mill ), so I tried transferring the code to a folder on the PC, and running it from there with the flash drive unplugged - same result. I've had this kind of problem before, but only very intermittently - probably just didn't rear it's ugly head in shorter files as often, so I could get through them after one re-start.

Here's my setup in brief - I can give more detail if necessary :

Dell PC with a Pentium 4 processor, 3 Ghz, 1 G ram, running XP SP3, dedicated for use with the mill - no internet connection, no music playing, etc. I have not uninstalled anything, so there may be unnecessary background windows stuff running - I'm a relative novice, so not sure what to look for, but happy do ditch anything that might help.

BOSS 9 bridgeport upgraded to a Galil motion control card, connected via ethernet crossover cable.

Mach 3 ver R3.043.066

I am way behind with my project, so any help / ideas / thoughts would be greatly appreciated!

Thanks, Alex

Sounds like the plugin is hanging for some reason, probably best to ask on the Galil section and maybe Steve will have an idea.
