Wow, while I've seen minor issues running on JDK 7 I haven't seen any
problem loading styles or connecting to shapefile/postgis.
As said, when I start GeoServer on my dev machine it often runs on Oracle
JDK 7.

I'm setting up a build server on OpenJDK 7 ( http://aaime.no-ip.org/jenkins/)
and fixing issues on trunk as I find them, right now it's still not building
but I believe I'm one patch away from making it work.

I've also been working on making the GeoServer build work at all on Windows,
that is already a reality, again, on trunk only (the fact that we build
successfully
or not on Windows has a weak correlation to the fact we can run on it at
all,
often problems are in the tests themselves).

I guess JDK7 + Windows might be a combination that causes even more
trouble...

Re: [Geoserver-users] [bulk]: WARNING Geoserver can damage your computer/server

[Ben Caradoc-Davies]

Nahum,

CentOS (and other Red Hat derived distributions) run a daily prelink 
cron job:
http://en.wikipedia.org/wiki/Prelink

This (or normal system updates) almost certainly explains the changes 
you see in libc.

A nonprivileged user will not be able to modify your libc.

JDK 7 is not supported. GeoServer failures with JDK 7 are expected.

If you see system corruption, you likely have a hardware problem. (This 
is now off-topic for this list.)

Please conduct the following hardware tests:

(1) Run Memtest86+ for 24 hours to test for bad RAM. This utility should 
be present as a syslinux boot option on all Red Hat installation media:
http://en.wikipedia.org/wiki/Memtest86

(2) Run mprime/Prime95 for 24 hours
http://en.wikipedia.org/wiki/Prime95#Use_for_stress_testing
You can obtain mprime (64-bit Linux) here:
http://mersenne.org/freesoft/

The command under Linux for stress testing is "mprime -t".

If your computer can run "mprime -t" for 24 hours without errors, your 
computer is "prime stable". This only tests your motherboard, CPU and 
RAM. If you see errors, it means that your hardware is unreliable.

Also install smartmontools and use smartctl to run HDD self-tests.

Kind regards,
Ben.

Re: [Geoserver-users] [bulk]: WARNING Geoserver can damage your computer/server

[cmaul]

Hello Nahum,

I have put the Oracke JDK 1.7u9, which is the same as yours on (WinXP,
geoserver2.2/2.1.3, geowebcache1.3R1, geowebcache1.2.6 Tomcat
7.027/Tomcat6.0.35 all on Oracle 10, Oracle ArcSDE9.2 and PostGIS) and yes
you are right it does not work, none of them worked. Start-up fails with
absurd errors about not being able to read certain SRS, SDE connections fail
or if it starts SLD aren't read and the map turns up white on white
background and the entire computer is slow as a wet week, etc. I didn't
investigate the various errors as I needed it working and thus hadn't the
time to do so.

Not much of a surprise as Geoserver wants a JDK6. BUT on deletion of the
JDK7 and all its traces everything went back to normal! 

I am not disputing your hardware problems, but I think we are dealing with
two unrelated events here, which happened to occur close to each other.

Cheers

Christian

Found It!

Seems to jdk 1.7 update 6 to 1.7 update 9 corrupt in some way glibc, I made
a md5 checksum on all my library files and after setup with those jdks and
after running geowebcache in several layers I noted changes  glibc, with a
diff the chechksum of glibc change.

Odd. :(

Do you know any tool to investigate such changes?.

Thanks in advance.
Nahum

Btw, "faulty hardware" does not necessarily mean the computer itself,
motherboards
often "fry" due to power issues, it may be that GeoServer is loading the
machine
more than other software, which makes the CPU/motherboards require more
current, which in turn
triggers the problem in your electricity source

Just noticed now that you're using JDK7. GeoServer is not tested on such
JDK,
in fact we know some minor functionality does not work properly with it.

That said, I've been running GeoServer for development purposes on JDK 7
since a few months ago, using Oracle JDK 7, on a Ubuntu 64 bit box,
and have seen no issue so far

CentOS + Oracle JDK is a very common setup, as well as PostgreSQL, and yet
it's the first
time we hear such a report.
I agree with Stefan this looks a lot like faulty hardware, your accusations
are grave and you
should verify better before making such statements on a public list,
especially writing
them as "truth" instead of asking around what the possible cause is.

There is not the case. That was the first ting I thougth, but all three
computers were damaged at diferento locations, seems to be oracle jdk,
right now I'm running authopsy.

I was running geoserver as a normal user not superuser.

The linux version I'm using is CentOS x86_64.

With FreeBSD there is no problem.

Re: [Geoserver-users] [bulk]: WARNING Geoserver can damage your computer/server

[Stefan Engelhardt (HBT)]

I am sorry but I can not imagine, that a piece of normal software can damage 
your pc. I first would search for the problem in your hardware environment for 
problems, perhaps to warm or to high voltage.

Subject: [bulk]: [Geoserver-users] WARNING Geoserver can damage your 
computer/server


Hello All.

I've found that geoserver under some very rare circunstances, can 
render your server/pc unable to run geoserver again.

Check this:


*   Geoserver only distribute layers from postgresql/postgis 
*   Begins to loose connections with postgresql. 
*   Crash geoserver. 
*   Even reinstalling the server don't work (Linux OS, JAVA, TOMCAT 
from fresh sources).

I have One HP server ProLiant DL300 who only replacing the motherboard 
worked again. Also have a workstation Dell Precision m6600 which I replaced the 
motherboard.

Today it damaged my PC with motherboard Intel and Core i5

I think the server and the workstation where damaged at factory, but 
today it damaged a brand new PC. 


All three computer get damaged in diferent locations.


I suspect the culprit is jdk 1.7 and geoserver trigers the problem.


Here are the exception even if you reinstall the OS and software from 
fresh sources.
