Re: w3wp.exe using 99% CPU and 1gb of RAM

Well, had another issue on Day 6... will call Swiftpage, once again, tomorrow to try and get this resolved. It's been 8 hours since I had an issue this morning and the CPU usage is already up near 60%.

Re: w3wp.exe using 99% CPU and 1gb of RAM

I had the same trouble on v21.1.187 update 3 with webapi_v1.0.449.0. It was the web api application pool using all cpu. I had to kill the w3wp process remotely so I could get into my server as it was slowed to a crawl. I went into the advanced settings of the web api application pool and set a cpu limit of 25% with a kill order after 5 minutes. I haven't noticed any trouble with it since then. That's not to say it doesn't happen, I just don't know now. I suppose there must be a log of kill actions somewhere but no clue. See attached photo for reference.

Hi Seanster2,

 

a good tip with the cpu limit parameter.

 

Before you set this parameter, you'll have to verify your version of IIS:
