[Exist-open] Database corruption mystery

[Joe W. <jo...@gm...>]

Hi eXist list,

In the past few days I've encountered problems with a fresh
installation of 1.2.4.  I'd appreciate any assistance troubleshooting.

Here's what's happening:
- I use the java admin client to restore my files from backups created
using the java admin client (3.5 megs zipped, 7 megs unzipped, 3,635
files, 25 folders; + 12.5 megs of binary jpg/pdf files)
- The logs show all of the files were successfully uploaded
- The website I'm serving from eXist appears to be working just fine
- Then the logs begin to show exceptions, then the server becomes unresponsive
- I have our server admin shut eXist down, remove the .dbx and .log
files, restart; I restore files from backup again; the problem starts
again
- I had no such problems using these same files on my home machine
(iMac intel running a stock 1.2.4 installation)
- I'm clueless about what's causing this on the Windows server - could
it be memory settings?

First, I'm running eXist using the wrapper tool on a Win2K server,
with the following memory settings:
- exist/conf.xml:
    <db-connection cacheSize="48M" collectionCache="24M" database="native"
        files="webapp/WEB-INF/data" pageSize="4096">
- exist/bin/startup.bat:
     set JAVA_OPTS="-Xms16000k -Xmx128000k -Dfile.encoding=UTF-8
-Djava.endorsed.dirs=%JAVA_ENDORSED_DIRS%"
- exist/tools/wrapper/conf/wrapper.conf:
     # Initial Java Heap Size (in MB)
     wrapper.java.initmemory=16
     # Maximum Java Heap Size (in MB)
     wrapper.java.maxmemory=128

Second, here are the exceptions - they reappear over and over:

Can anyone can divine what is going wrong from reading these errors?
I'd be grateful for any suggestions!

Thanks!
