An infrequent, but recent series of JVM crashes under the configuration of CFMX 6.x on JVM 1.4.x on the Linux platform has been resolved in the short term with the -Xint JVM argument to disable the Sun JVM HotSpot optimizer. The -Xint JVM option, described in this Sun VM Options page, can be added to the JVM argument list in the ColdFusion Administrator to force the JVM to run in the interpreted mode, avoiding HotSpot optimization all together. The result is more stability in exchange a performance hit. While a better solution is being sought after, the -Xint option will work in a pinch.
