CAN calls freeze system

[NJKirchner]

I have a system w/ a series 2 PXI CAN card.

I am communicating in both directions, receive @ 1000S/s and send at 100S/s

Randomly, my system completely locks up w/ no recovery except hard shutdown.

Occasionaly, before the lockup I get an NI CAN Error stating to look at the NICANERR.txt

as follows 

Any clues?

Hi NKirchner,

Please provide more information about your System. what kind of CAN device are you using (HS, LS XS). Which baudrate, how many channels, how many CAN boards are you using?

I know it is not that easy in your case, but it would be great if you could create a Spy Log file using the NI-Spy Software.

This tool comming with the driver, logs all API calls and you can save the file after stopping it in error case.

Thanks

P4 w/ HT Turned off 1Gig Ram

MXI-3 copper card wired to PXI chassis w/ CAN PXI-8461 and a few other cards(DIO, CTR, MIO).

Note: This system is identical to 4 other ones that have no problem, so it's not a compatibility issue w/ the other cards. Also the other systems are running the same software. Also we have already switched CAN cards, updated the driver, and have tried another new PC.

1 CAN board, using 1 port, w/ 1 device on the lines.

Hi NKirchner,

have you tried to use an other MXI Bridge with this hanging system? perhaps there is something wrong with the MXI?

Replace the PCI MXI portion and the cable.

I have a sneaking suspicion that it might be error due to line noise on the CAN TX/RX lines.

I would have hoped that the system would not totally freeze up if there was comm errors but it's looking more and more likely

Have you seen this kind of behavior in that kind of situation?

Hi Kirchner,

Are you saying that you have replaced the pci-MXI portion? If so, are you seeing the exaxt same results?

I don't think you should be seeing your system crash due to CAN noise.
