- Strange ColdFusion issue, JRUN eating up to 50% of CPU.
For one of our project we recently move to Amazon EC2 to make system easily scalable. This is kind of seasonal website which has high traffic during September and October and rest of the year traffic reduced to 70% with compare to October month. I think Amazon's usage based model is perfect for this client as he doesn't need to pay much on his off season also we can easily scale and add new instances during peak season and cover cost that we saved during off season.
Finally we happily moved everything on cloud EC2 and working fine. Suddenly after 1 hour of so CPU usage increased to 50% and remain constance 50% for hour or so. While looking into Task manager we realize that JRUN is eating up that CPU but there wan't much traffic at that time (average 1 user/sec) and system was happily handling this much traffic in our dedicated server. Tried to install Fusion Reactor to see realtime users and other stats but it seem that even Fusion Reactor can not figure out who is eating up CPU. For a day we keep running server as our all sites working correctly and wasn't making much performance issue.

- Configure ColdFusion with VisualVM.
For one of our project we are facing jrun high usage issue. When looking into task manager (Window 2008) I found jRun continously eating up 50% CPU usage even though there is no traffic (or may be 2 to 3 users) only on site. Initially I tried to install FusionReactor to get all kind of detail regarding ColdFusion. Started with trial version and thought if useful then get full version but it seems that giving me all application ColdFusion application related information but can't find anything why JRun eating 50% of CPU usage. After bit googing I found VISUALVM and JConsole for monitoring and troubleshooting java application. I like VisualVm due to it's nice GUI and also I can integrate JConsole as plugin to it. It win - win kind of situation.

- Task Scheduler was not working Social Engine video upload module - Solved
Hi,
Recently I started reviewing SocialEngine (Short desc: create your own social networking site), and I face some issue with video uploading process.
I am using SocialEngine 4.1.7.
By default, user can only embed Video from YouTube and Vemio. But if you want to upload the Video file, you need to allow it by enabling settings from the Administrative area.
