SysPlant.sys - Windows BSOD Issues

This issue has been solved. See solution.

Hi All,


I have been having some issues with BSOD on a few workstations that have been caused by SysPlant.sys on a regular basis. What exactly does SysPlant.sys do? Also, What risks or repercussions would I see if I disabled the sysplant driver in device manager. Are there any known issues with sysplant.sys and other software?


Currently, we are running SEP 11 (MR2) without application/device control enabled. 

Any info would be great. Thank you for the time.

Sysplant.sys is our Application and Device Control driver. Since you are not using this functionality please feel free to disable the driver as it will cause you no issue.


There has been some conflicts in the past revolving around Sysplant and most of them have been addressed throughout the different releases of Endpoint Protection. If you wish to keep this driver enabled then I would recommend you migrate to the latest version 11.0.3001.2224 and see if that resolves the BSODs. If after migrating to MR3 you still experience BSODs relating to this driver I would suggest you open up a Technical Support Case with us so we can collect a Memory Dump and determine why you are getting them.


Hope that helps!

We had a similar issue with another customer running Oracle who would see the same problem.

In their case, it was fixed by upgrading their SEP client to MR4 MP1.

If you get the client only patch from here:

you can try it on a single machine to test, but I'm fairly optimistic.

I have the same random BSOD on machines using a Logitech wireless Bluetooth keyboard and mouse. It doesn't effect the other machines as far as I know. I have a feeling it is the USB Bluetooth transceiver causing the problem. I'm going to try to make an exclusion and add the device to the allowed devices to see if it helps. Otherwise were back to replacing the wireless keyboards with wired units as a workaround.

I have seen few instances recently with 11.0.4202.75. I never installed any old versions, so not sure this BSOD on Sysplant.sys was just in this version or also existed in other older versions.

During a 2-week priod we had BSoD on 577 workstations of the ~3000 where SEP11.0.4202.75 has been rolled out.
We have an open case, but i think it's better to wait for MR5 (due to release in September) and play the send-me-more-logs-again-before-i-tell-you-something game with the Symantec support only if the issue will still exist.

during from 1 sept until now we have only 11 clients that has bsod, and the common with this is the wlan card,  it is INTEL 4965ag/agn

we have around 2000 clients and of those there is 650 with this wlan card... and untill now only 10 clients has bsod... 

we have tryied diffrent drivers etc...

but we also have a open case,..  so we will wait untill MR5 and see.....

is there anyone that have notice this?

we have also seen several Sysplant BSODs. Investigating and getting memory dump analysis.
SEP MR3. We are currently preparing MR5, whcih we will test on affected machines if Symantec so advise.
