Generate a dump file

Hi Christophe,

I would be curious to know if the high CPU usage is caused by the w3wp.exe process.
We have the same issue. We’re on v15.4 SU9, and we suddenly had an issue whereby if any of the custom reports were including images, the report would sometimes get stuck trying to generate and cause the w3wp.exe process to spike to 25%. Then each time it gets stuck, generating a report, it increases another 25% until the CPU’s running at 100% and everything grinds to a halt.

We made the ‘sub-reports’ that grab the images ‘invisble’ so they’re no longer grabbing the images, which seems to have solved the issue on our application servers (although we still hope for a fix so we can reinstate them), but at the moment, the mobile server still has an issue where the w3wp process causes the CPU to grow until all mobile activities don’t work.

This is still being actively investigated for us.

cheers

Hi Mark,

Yes it was cause by the w3w process. in our case today we have been able to indentify the cause and i will log a ticket to the support.A user wanted to import data from an import template with an excel file which was protected. he tries to import click on import button nothing happens (the cpu of the server increase up to 50%) then click again several times on the import button so the CPU was then 100%.

We have already also encountered CPU consumption with report and image, the symptom was if the image extension was .jpeg it was ok no issue  but if it was .JPEG we had issue with cpu growing to 20% then if the same report was launch again cpu growing to 50% etc .. if it is your case you need to check the HasImageExtension function in your report for example we have defined 

validImageExt As String() = {".jpeg", ".jpg", ".bmp", ".gif", ".png",".JPEG", ".JPG", ".BMP", ".GIF", ".PNG"}

Hi Christophe,

Thanks for your reply. That’s very interesting and good to know around the import of a protected excel file. I’ll have to remember that, in case we ever encounter similar.

With regards to the report with image issue you experienced, was there a fix for that scenario?

Cheers
Mark.

Mark

if you have the same issue on the report we had for one of our customer the fix was to add in 

validImageExt the file extension in upper and ower case like you see in the example below

validImageExt As String() = {".jpeg", ".jpg", ".bmp", ".gif", ".png",".JPEG", ".JPG", ".BMP", ".GIF", ".PNG"}

. But perhaps your issue is different.
