Rebooting system due to exception

[SarahW]

Hi,

I've recently installed LabVIEW 2010 and re-deployed an RT exe which worked fine in LabVIEW 2009. The RT system now works for a bit and then crashes, giving the error message:

Rebooting system due to exception

Flushing disk cache....

Attached is the rtlog error file generated, any ideas how I interpret this file?

Thanks for looking,

Sarah

Hi Sarah

I have a few more questions to see what could be coursing the issue;

Have you updated the real time on the RIO for 2010?

Is there a code attached to the error message?

Are you logging to a file?

Are there any other applications on the RIO?

How long after the application starts does this take before the error occurs?

Hi Robert,

Thanks for the reply.

It's a real-time PXI and I have updated it for LabVIEW 2010.

I can't find an error code anywhere.

I do log to file, the program reads some analogue inputs every 20ms and adds each reading to the sum of all the previous readings. These totals are saved to file once a second so if the PXI crashes the totals are saved and can be reloaded when the PXI starts up again.

There is just the one application running, it does a few other things like checking the time so it can reset the totals at midnight, calculates averages of the readings and reads the time from an NTP server to make sure the clock doesn't drift.

The application normally runs for a few hours (sometimes up to 6) before it crashes.

Many thanks for taking a look.

Hi,

Attached is a copy of the RT part of my project, any suggestions welcome.

Many thanks

Hi Sarah

Have you had this set up working before?

Make shore you have the correct drivers.

If it is a windows based controller reinstall all of the national instruments software and repair windows. If it is a real time OS (operating system) reinstall the OS.

The error you are getting as  this exception is generated by an illegal "memory access violation". On a Real-Time system, this is usually caused by either faulty RAM, an incorrect device driver, or corrupt software.

Hi Robert,

Yes, I've had this set up working with LabVIEW 2009.

It's a real-time PXI and every time it crashes I have to format the disk and reinstall the software through MAX.

It currently has the following installed:

AMD AM79C972 10/100Mbps Ethernet Driver 1.0.0.3.0

Broadcom 57xx Gigabit Ethernet Driver 3.0.0.3.0

HTTP Client 1.1

LabVIEW Real-Time 10.0

Language Support for LabVIEW RT 1.0.0.3

Network Variable Engine 1.7.0

NI System Configuration 1.1.3

NI System Configuration network support 1.1.2

NI Web-based Configuration and Monitoring 1.0.0

NI-DAQmx 9.2.3

NI-Sync 3.2.1

NI-VISA 5.0

Remote Panel Server for LabVIEW RT 3.0.0

Run-Time Engine for Web Services 3.0.0

Variable Client Support for LabVIEW RT 1.7.0

Is there anything obvious missing?

Many thanks,

Sarah
