Hi Matt. I develop the vi's on a MicronPC, Pentium 4, Running Windows XP Professional. The (4) PC's in our mfg department are newer HP Workstation xw4100, Pentium 4. (3) of these HP's are 'H T', and (1) is just the 'H' (single processor?). The machine that is only the 'H' does not have Windows Office, or Outlook like all of the other PC's. It also has never 'locked up' like the other (3) PC's. The lock up is very intermittent. I test PLC I/O cards which are typically (8) channel cards. The lock up usually occurs when I am looping through the (8) channels. I use different loops for different applications, mostly for, and while, and I always make sure to put a 50-150ms wait in each loop. I am using LabVIEW 7.0, NI-488.2. The PC's are a
ll PCI, with IEEE GPIB cards. The techs say that these programs dd not lock up with LabVIEW 5.0. We upgraded within the last year to LabVIEW 7.0. Symantec Antivirus, full version 8.1.0.825. So to sum it up, the only commonality is the (3) PC's that lock up have the HT Pentium processors (and have Windows Office, or Outlook), while my PC, and the other one just has the single processor, but my PC does have Office, and Outlook. Our IT guy restricts permissions to the techs, but I have logged into a PC that locks up, and have had our IT guy give me full permissions to that machine, and then let the tech test away, and lock ups still occured. Kinda rules out the administrative rights theory.
The lock ups are very intermitent, sometimes an entire day will go by with no lock ups (rare), but usually it happens ~6 times a day.
Sorry if this seems a bit jumbled, but I am just trying to get as much info down as possible.
Thanks, for your help.
