I am using geoserver and I started to get a strange java error
message. I did some google searches for
'java.io.IOException: FULL head' which led me to think this could be
an obtuse problem. I had posted this on the geoserver users group, but
it is a small forum for one.

Any help would be appreciated even as to what to try or google search
for as I am somewhat lost on this. My original post for geoserver
forum is below - thanks

===================================

I had geoserver working fine for a couple months serving WMS and WFS
content on my site through postgress that I had been working with.
Today all
of a sudden the content no longer shows on the map and I started
getting the
http 404 error below from here when I try to go to the geoserver
itself:
http://myhost:8080/


Error 404 - Not Found. No context on this server matched or handled
this
request.
Contexts known to this server are:

-
/javadoc --->
org.mortbay.jetty.servlet.Context(a)48ff68{/javadoc,file:/usr/local/
geoserver/javadoc}<http://grp106-katana.llan.ll.mit.edu:8080/javadoc>
-
/geoserver --->

local/geoserver/webapps/geoserver/}<http://grp106-
katana.llan.ll.mit.edu:8080/geoserver>



=======================


If I go to http://myhost:8080/geoserver or
http://myhost:8080/geoserver/web
it show nothing in the browser and the console log shows:

Did you find this one?
I'm sure I don't know what it means re your problem.

I was aware that there are various strange bugs that have the same
stack dump.

I have been using a centos 4.7 or some such and had some other odd
problem trying to upgrade firefox and am wondering if I should switch
to fedora and maybe that will help. Other than that I'm not sure what
to do. It seems possible the error occurs in some java binary code so
I can't analyze the source code, still need to look at that some more
maybe.

This also illustrates a problem regarding using geoserver which is a
critical part of the architecture for serving WMS styled xml from
postgress/postgis database tables, something that seems difficult to
do any other way, but if it has the potential of bombing out like this
it scares me a bit. The best thing I can recommend is that when it is
deployed, try to dedicate a machine to run geoserver and don't upgrade
it's software components where not critical .. I had recently tried to
install some wiki software and sometime after that the problem
occured, not sure if it's related, one was tracwiki which is python
based and uses easy_install, the other was various instiwki packages,
which is ruby

I was thinking maybe I'd find the source code here, but I don't see
the java files I was was looking for:

I think Jetty is in the process of changing homes.
<http://www.eclipse.org/jetty/about.php>

Is it possible for you to abandon the Jetty embedded
container in favor of an external servlet container?
