Interesting and thanks for your response. We switched back to VM version 1.6.0_07 (64 bit on Slackware) and everything was fine. For several unrelated reasons, we switched to Tomcat version 6.0.35 and JVM (Oracle) version 1.6.0_16 and all has been fine for a month or so. The cause remains unknown but seemingly gone now.
