High CPU with Chrome

Jump to solution

We're at DLP 11.4 and experiencing high CPU with Chrome. I am wondering if we have not updated our Supported Chrome versions since 2015, if this could be an issue. The last supported version is 42.0.2311.90.

Can someone explain why we may need to updated Chrome's supported versions and if not doing so could explain the high CPU when using Chrome?

Hello Submerge,

 

Thank you for choosing McAfee Support Community

 

DLP has re-introduced functionality supporting the blocking of chrome file uploads in Endpoint DLP.

Chrome v72 and above will be officially supported.

-DLPe monitors all HTTP & HTTPS requests (GET, POST, PUT)

*File upload

*Drag and drop of a file on a web-page upload(eg Dropbox)

*Web post of test (Body of Gmail,  yahoo)

-Each browser has proprietary code that used to perform HTTP/TTPS requests

-By inserting DLP code between browser and the OS, Mcafee can monitor/block browser activity and inspect any files or text being sent via POSTs

-Chrome code for performing HTTPS request is significatly less standard and harder to intercept than the code for IE and firefox.

Hi @Submerge ,

Kindly check out the Handle counts in the task manager when you are experiencing high CPU usages and sort the handles count in descending order to see which process has more handles,

If fcag.exe or fcags.exe has more handle counts more that 5000 or 6000 kindly let us know.

Thank you.

Hello, 

We are seeing high handles count, often in the 100K range. DLPE version is 11.4

This is on a developer machine with plenty of CPU/Memory resources. 

We have taken steps to trust the some of the applications on the machine however still seen high counts. 

Please advise 

Thanks

Hello,

There is a known issue in both DLP 11.3 and 11.4 involving high handle counts with the fcags.exe process. This issue has been resolved in DLP 11.5. I would recommend upgrading to this version and see if the overall system performance improves.
