BSOD Need dump file help

[danmkennedycx]

I am running automation software instances simultaneously and it is causing the Multiple IRP error. Any help is greatly appreciated.

Thanks,

Dan

danmkennedycx, Wht your dump files are saying is

Svk2pl64
start             end                 module name

MULTIPLE_IRP_COMPLETE_REQUESTS (44)
A driver has requested that an IRP be completed (IoCompleteRequest()), but
the packet has already been completed.  This is a tough bug to find because
the easiest case, a driver actually attempted to complete its own packet
twice, is generally not what happened.  Rather, two separate drivers each
believe that they own the packet, and each attempts to complete it.  The
first actually works, and the second fails.  Tracking down which drivers
in the system actually did this is difficult, generally because the trails
of the first driver have been covered by the second.  However, the driver
stack for the current request can be found by examining the DeviceObject
fields in each of the stack locations.

I suspect you have multiple instances of that and are conflicting with each other. The driver is seriously out of date, You will need to update the drivers at a minimum. Your hardware may not be able to run multiple instances.

essenbe,

Thank you for your support. I have looked around online and my computer indicates that I do in fact have the most up-to-date driver for the Gigaware USB-Serial adapter. I read that other people had better success with other adapters that have "superior build quality". I ordered one to see how it goes. Just for information: I am using only 1 Gigaware adapter to communicate with a device controller. This never seems to be an issue until I start running an Automation platform locally on the same machine. I'll keep posting if the new device does not solve the issue. Thank you!

That driver is dated 2010 and the problem seems that more than one IRP is requested for the same thing. So, I really don't know unless there is a driver conflict with your automation software, or perhaps they are both calling for the same packet. Just let me know, these things can be a real pain sometimes.
