[FDS-106] JVM Memory Leak With Attached Language Debuggers
Description
JVM Memory Leak With Attached Language Debuggers
Sun identified a fault with their JVM product (on which most CFML engines run) which can cause memory to leak when a language debugger is attached and access the target machine in a certain (well-documented and Sun-approved) way.
Sun are tracking this issue under bug ID 4858370 here:
http://bugs.sun.com/view_bug.do?bug_id=4858370
Symptoms
During a long debugging session, you may find that the target JVM memory usage increases by a small amount, which is never reclaimed by Java. Under tests, FusionDebug was shown to have a minimal drain on memory due to this issue.
Fix
Since this is a known issue with the JVM, a Sun Microsystems product, it will be solved in a future JVM release. Customers should generally not experience this issue except when performing extremely long debugging sessions. Memory is reclaimed normally if the JVM is restarted.
