I wrote a VI for controlling 3 New-Era syringe pumps and a Eurotherm 3216 temperature controller. The 3 syringe pumps are piggy backed one after the other, and the first syringe as well as the temperature controller are connected via USB-to-Serial to a YOGA2PRO idea-pad running a 64bit Windows 8.1 running Labview 2013 My problem is that the program causes windows to crash, resulting in the blue reboot screen with the error "Multiple_IRP_complete_requests" This error occurs at different stages of the programs and can occur after 10 mineuts or after an hour of running. When I transfer the exact same VI to a 32bit Windows XP Lenovo running Labview2012 the program runs without a glitch! I tried rewriting the VI to account for communication collisions or timing issues but havent been able to solve this mystry! For now Im running my program on the "old" computer, but I would greatly appreciate any help or suggestions on the matter.
