We have an application that has been in development for more than a year now. The number of interactive users is still small, but it has grown recently. Associated with this recent growth in realtime, day-to-day use is an alarming increase in system failures:
tomcat seems to get inexplicably hosed, at seemingly random intervals.
The $JAKARTA_HOME/logs files have (so far) revealed nothing helpful. ps uax | grep jakarta reveals the expected number of processes, but nothing works: not even the :8080 manager servlet.
bouncing tomcat seems to bring everything back up again. Is it our code or Xindice that is trouncing jakarta?
We're running java version "1.4.2_04" on a SuSe8.1 on a standard linux box, with a gigabyte of memory.
jakarta-tomcat-4.1.29 We start jakarta with JAVA_OPTS="-Xms512m -Xmx512m"
xml-xindice1.1b3
Any degbugging suggestions would be greatly appreciated. I'm at a loss as to how to track this down.
