Hi!
We run a webbased system using tomcat and apache. Some servlets
need the AWT to draw images, so we use an X server, Xvfb, and
it usually works dandy.
Lately, we've seen systems under high load losing the
connection to the X server (I think?), and the JVM has to be
stopped and restarted for it to start working again.
Here's the stack trace. The named class,
sun/awt/X11GraphicsEnvironment, exists in the path, of course,
and this works for days or weeks until it fails. Once it fails,
it fails all the time.
2001-09-13 03:05:57 - Ctx( ): Exception in: R( +
/servlets/ChartGen + null) - java.lang.NoClassDefFoundError:

FreeBSD-4.3, native jdk1.2.2b10, XFree86-3.3.6 running as:
/usr/X11R6/bin/Xvfb -fbdir /var/tmp -screen 0 320x200x24
Any ideas?
