CF 11 High CPU Fresh Install

forums_noreply@adobe.com — Wed, 13 Aug 2014 14:26:11 GMT

Hi,

We seem to have run in to a problem with two CF instances having high CPU usage after 1-2 hours.

We have three servers, two of which are back ends to a load balancer, the third is just on its own. They all have the default installation of CF 11 Enterprise running on W2012 R2 / IIS 8

I noticed that CF installed on the two backend servers started using a lot of CPU (30-40%) after a couple of hours, then as time went on further so did the CPU usage. If left overnight it would be hitting 100% constantly.

These are fresh installs and have no content being served except for the default web site in IIS. So this rules out dodgy code etc.

All three servers have the same software installed on them and the same IIS configuration. I went through the CF 11 lockdown guide to see if this would make any difference, the issue occurs with or without the changes in this guide. I have changed the jre to a different version and this has made no difference. I have made changes recommended for the workers.properties files, still the same.

The only difference between these two servers and the third server is that the two are behind a load balancer. This LB polls the servers to see if it will get a response. I enabled the firewall on one of the servers to block all incoming traffic and the problem has not occurred since. So I assume it has something to do with the request being sent from the load balancers?

They send OPTIONS request every 3 seconds to both of these servers that have the problem. Could this be causing a problem with CF 11??

I have looked at the threads through ProcExp when the problem occurs and can see the threads related to msvcr100.dll seem to be the ones that are using up all the CPU. This file is the same through out all our servers and even after reinstalls etc the problem still occurs, so I don't think this file is corrupt.

Any one got any other ideas?

Font Rendering Issue

Hi,

We seem to have an issue with the font we are using not rendering on pages and cfdocuments (PDF) correctly on occasions.

Our setup is IIS7, Server 2008 R2 64b and Coldfusion Enterprise 9.0.1 (Hotfix 2 applied).

We are using the standard windows Tahoma font, with all fonts showing in the Font Management in the administrator control panel.

We find that sometimes when creating the PDFs that they will just turn up in a font similar to Times New Roman. On fewer occasions some of the web pages will also not show the font correctly, but it seems to happen more with the PDF creation.

Leaving it some time and coming back it seems to just correct itself, then just as quick it will revert back to the wrong font.

We have played around with the fontembed option in the cfdocument tag, but seems to make no difference.

Anyone ever had anything similar or could give us ideas on where we could look to correct the problem. Its a live server, so ideally want to avoid reloading CF.

If you need anymore info, or I left anything out let me know.

Thanks in advance.
