--- Comment #5 from Steve Demy <steve.d...@shaw.ca> --- I believe the stack traces are generated from users connected by mobile devices (Vaadin Touchkit). These users connect to the LAN using wi-fi and may possibly exit and re-enter areas of coverage or change zones within a coverage area. Many sessions don't generate any errors. As far as I can tell from casual observation of past behaviour: 1) Use of NIO or NIO2 connectors makes no difference - a corresponding error is produced, 2) I tend to see the logs clean after a full system reboot, then errors increase over subsequent days. The system is dedicated to this one webapp and its few supporting applications and is lightly loaded. I use a cron script to restart Tomcat nightly in an effort to ensure that no memory leaks etc. accumulate. -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@tomcat.apache.org For additional commands, e-mail: dev-h...@tomcat.apache.org
