[Geoserver-users] Geoserver Services Stopped Unexpectedly

GeoServer GeoServer User

Hi all,

I’m developing WebGIS based to visualise spatial planning data, I have 50+ layers which primary store in PostGIS. I made connection from Geoserver to PostGIS and served all the layers as Web Map Services(WMS), openlayers been used as the webmap library to render all the layers and tools.

I developed the whole app (postgresql, geoserver, and web) on VPS which running on Ubuntu 14.04, 2 GB of RAM and 40Gb of HDD. The problem is geoserver services often suddenly stopped, I try to increase the java heap to 512Mb, turned off unused services like WFS, WCS but the problem still occurred, why the services often stopped?

Need advice from all of you guys who might have experiencing the same problem with me.

Thank you
Best

Hi,
what you’re reporting is not normal, but it’s impossible to tell unless you provide
more information.

What do you mean by services “stopped”? Do you have any interesting error in the
geoserver.log file?

Cheers
Andrea

Hi Andrea,

The Geoserver cannot be accessed at all, I need to restart the service again. I only see the error about failed to access one of data store connections which has not been used anymore, is it caused the services to stop? I put the error on dropbox Geoserver Logs 2015-10-17 and the full geoserver log in here. I am glad if you can take a look at the logs, because perhaps there may another activity/error that looks weird to you.

Thank you

Had a quick look in the short logs, and see this inability to decrypt a
password:

Caused by: org.jasypt.exceptions.EncryptionOperationNotPossibleException

org.jasypt.encryption.pbe.StandardPBEByteEncryptor.decrypt(StandardPBEByteEncryptor.java:981)

A situation that could cause this problem could be that:
* You had installed the strong encryption support in your JDK (to get rid
of the warning message in the GeoServer home page)
* The JDK got updated automatically, and the strong encryption support was
lost, causing the inability to decrypt the passwords.

However the above should make the server return errors when you try to
access the layers, but not "cannot be accessed at all"
like you describe, which I would interpret as no HTTP response at all

Cheers

I am using JRE 1.7.0 downloaded from oracle (not openjdk) is it caused the geoserver become unstable? There is no error logs that describe why the services suddenly stopped, isn’t it?

None. You can check on the GeoServer UI, status panel, and see if that's
what you're actually running.

Also, can you clarify what you mean by stopped? Are you getting back
service exceptions or just no response at all?

Stopped means The geoserver process suddenly disappear without any error logged on my server. I cannot access the geoserver from http, the map showed nothing all of my layers unable to load because it cannot find the geoserver services, the service needs to be started so that geoserver can run again. I put my geoserver status screenshot here
I already remove all unnecessary workspace, database connections, and services (WCS and WFS).

Oh ok, that means it's a hard JVM crash (could be a segmentation fault or
other problem).
You should find files named "hs_err_pid<numberHere>.log" in your file
system,
they normally are in the directory where the java virtual machine was
launched, which can provide
some information about it.

You should find files named "hs_err_pid<numberHere>.log" in your file
system,
they normally are in the directory where the java virtual machine was
launched, which can provide
some information about it.

On Ubuntu you should be able to find these files using (as root):

updatedb
locate hs_err_pid

You will need to examine the times on the files to identify the one corresponding to the crash. Please email this file to the list.

It is possible to have multiple Java implementation installed. It would be most useful to confirm the JVM version both in GeoServer and at the command line with:

ps -fwwC java

java -version

You can find all the installed java versions with:

update-java-alternatives -l

dpkg -l "openjdk*" "oracle-java*" | cat
