A Java Out-of-Memory Error involving GZIP, Typica, and SimpleDB
UPDATE
I am providing an update here to the root cause.
Overview
I ran into an interesting Out of Memory bug this week. It occurs if you use gzip to send/receive data and under-utilize your Java Heap memory. This land-mine has existed since 2004, though hopefully you will not be bitten by it.
Problem Stack
A Java process was throwing the following Out-of-Memory Error.
JVMDUMP013I Processed Dump Event "uncaught", detail "java/lang/OutOfMemoryError".
