OOM and HotSpot Bombs

Looks like I better hasten my effort to upgrade to Roller 2.x. This (v1.1) installation hit an OutOfMemoryError a little while ago and crashed the JVM in all of its hotspot glory. I'm suspicious of the caching implementation in Roller (IIRC, it's OSCache). For a non-clustered installation, plain-old-filesystem caches JFW. For distributed caches, JFW applies to memcached. We've been using the Java clients (and Perl and Python) for memcached productively for a long time now. Interestingly, some one was inspired to write a Java port of the memcached server. Crazy! And I think to myself, what a wonderful world.

Technorati

Who?

I'm Ian Kallen. I'm an entrepreneur and technologist working on Blockboard. My technical interests are focused on mobile, location, cloud computing, big data, real time event systems, search, devops and agile web application code. I'm a long time open source enthusiast and enjoy right-sizing code architecture and infrastructure with the scope and stage a technology startup is operating at.

Previously, I was an independent technology consultant. Prior to that, I did a long stint with Technorati leading the Core Services engineering group in architecting a backend to support search and exploring the web as it changes in real time. I have an eclectic background in technology, publishing, social software and ... life. I like to think: well rounded. I have been online participating in virtual communities since 1988 and developing online resources, services and systems as well as enterprise software since 1991. Once in a while, I have time and inspiration to blog.
