I'm currently trying to recruit a systems developer to join the 192.com Development Team in what I think is a very interesting role. In order to support the development of the product and its new features while maintaining the existing version, I'm looking for someone to take care of the day-to-day bug fixing and optimizing the existing production site and working on small to medium sized projects mostly related to the version of the product currently in production. The second part of the role has more to do with system engineering rather than development. While the majority of the team is working on new products and features, we also need to set up & streamline deployment processes, application server configurations, application monitoring and statistics, stress testing and benchmarking. You will also be responsible for deployment to the production environment as well as looking after the application server configurations.

I'm looking for a candidate who is fairly new to ColdFusion but with exposure to the popular frameworks & technologies in the ColdFusion community. Think of MVC frameworks (ModelGlue, Mach-II, Fusebox) , DI/IoC containers (Coldspring, Lightwire) and Unit testing (MXUnit, CFCUnit, CFUnit). The second must-have is related to the system engineering side of things, you need to have experience working with a Linux/Unix/Solaris system so you can set up and configure web & application servers (apache, tomcat, coldfusion) and troubleshoot any performance issues on the box.

Have a look at the job description, and if you're interested please send an email with C.V. to remy.becher at 192.com

We've upgraded one of our production servers to Coldfusion 8 last week in order to have a head to head performance comparison between cf 7 and 8. The installation went all smoothly but after a couple of hours in the cluster the error logs all of a sudden spiked with the following message:

Error Executing Database Query. The TCP/IP connection to the host has failed. java.net.BindException: Address already in use: connect

The error only occurred only on the SQL Server databases and only when connecting to the high volumes databases like the main transactional database. I'd seen this one before while tuning data sources; it basically means Coldfusion can't make any new connections to the database because it runs out of available ports. This can happen if you disable connection pooling in the driver (the "Maintain connections across client requests" tick box in the advanced data source settings) or enabling the "Limit connections to" setting and specifying a number too low to serve all the requests.

Neither of the 2 settings were in use though...so why wasn't it pooling the connections? We're using the Microsoft SQL Server 2005 JDBC Driver 1.1 instead of the build in (Data Direct driver) because I've been told by the Fusion Reactor guys they're flaky. And all our data sources are wrapped in the Fusion Reactor wrapper for real time monitoring.

So 2 things to try: running the server without Fusion Reactor wrapping, no luck, and secondly connecting to the affected data bases using the build in driver instead. And the problem disappeared. Having run all our production servers with this driver for months now without any issues I'm pretty sure it has to be something else so I suspect the driver isn't compatible with Java 6. I can't find anything on the net about this yet though...I would have expected others to have similar issues.

MS recently released the CTP of version 1.2 of the driver so I might give it a test drive to see if it contains the same bug. CF8 is definitely a lot faster then 7 though...
