Fehlermeldung: 503 - Service Temporarily Unavailable

[zwelch]

Hallo Forum!

Ich habe heute fast erfolgreich und gemäß der Anleitung "Open-Xchange Community Edition" auf meinem Server (OpenSUSE 11.1) installiert. Leider erscheint, wenn ich mich in der Groupware einloggen will, die im Betreff genannte Fehlermeldung.

Ich vermute, dass der Groupware-Dienst sich nicht zum starten überreden lassen will und deshalb diese Meldung erscheint. Wenn ich folgende ausführe:

ns1 ~ # rcopen-xchange-groupware start
Starting open-xchange-groupware daemon                             done

Gibt es folgende Meldung im Log:

ns1 ~ # cat /var/log/open-xchange/open-xchange-console.log
Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.

Im Server selbst stecken zwar nur 512 MB RAM (und lassen sich leider auch nicht aufrüsten (embedded)) aber, es ist eigentlich genügend frei.

ns1 ~ # free
             total       used       free     shared    buffers     cached
Mem:        448584     243024     205560          0       9184     127248

Swap:            0          0          0

Jetzt die Frage: Ist mir noch zu helfen () und wenn ja, wie?
Danke.

// Edit
// Ich glaube es müssen 2 Java-Prozesse laufen. Tun sie aber nicht.

Hi,

like you've already mentioned the problem here is memory. Open-Xchange does not require much memory but the JVM is caching as much as you've configured. I guess we need some manual configuration here to make it work. Please take a look at this file

/opt/open-xchange/etc/groupware/ox-scriptconf.sh

This file configures the java virtual machine. There are settings for maximum and even minimum memory usage, if the minimum or maximum is higher than the available memory, the JVM does not start. Please post the content of this file (the JAVA_XTRAOPTS line) so we can do some tuning for systems with low memory.

Greetings

hi,
here ist the file.

ns1 ~ # cat /opt/open-xchange/etc/groupware/ox-scriptconf.sh

PROPERTIESDIR=/opt/open-xchange/etc/groupware
COMMONPROPERTIESDIR=/opt/open-xchange/etc/common
LOGGINGPROPERTIES=/opt/open-xchange/etc/groupware/file-logging.properties
OSGIPATH=/opt/open-xchange/etc/groupware/osgi

# This properties sets the java options given to the groupware on start
JAVA_XTRAOPTS="-Xms512m -Xmx512m -XX:+UseConcMarkSweepGC -XX:NewSize=256m -XX:MaxNewSize=256m -XX:SurvivorRatio=6"

# Maximum number of open Files for the groupware
NRFILES="8192"

# Specify the umask of file permissions to be created by ox, e.g. in the
# filestore.
# BEWARE: setting a nonsense value like 666 will make open-xchange stop working!
#         useful values are 006 or 066

Hi,

okay the problem is that the JVM is configured to a minimum of 512MB reserved memory which is clearly too much for your server. I'd propose this config:

-Xmx384m -XX:+UseConcMarkSweepGC

You can remove or uncomment the previous settings. This new setting configures a maximum memory consumption of 384 MB, but you can configure it to be higher or lower.

Good luck!

[zwelch]

it works!
thanks a lot!

Sorry, dass ich mich auch hier drann hänge.

Ich bekomme die gleiche Fehlermeldung...

Mein Rechner hat aber 1024MB und es laufen 2 java Prozesse (/usr/bin/java und /usr/lib/jvm/java-1.5.9-sun-1.5.0/jre/bin/java)

Den OX-Server habe ich gestern frisch aufgesetzt - und es war noch nie eine andere Version draufgewesen.

Auch ein wechsel der JAVA Version ändert nichts am Fehler.

Beim Login-Versuch wird die Logdatei open-xchange-osgi.log geändert:

Hi,

please check the file permissions on this directory and subdirectories

/opt/open-xchange/etc/groupware/osgi/

this should look like this:

drwxr-xr-x 4 open-xchange open-xchange  4096 2009-08-26 16:42 .
drwxr-xr-x 6 root         root          4096 2009-08-26 15:56 ..
drwxr-xr-x 2 open-xchange open-xchange 12288 2009-08-26 15:53 bundle.d
-rw-r--r-- 1 open-xchange open-xchange 10189 2009-08-26 16:42 config.ini
-rw-r--r-- 1 root         root          3061 2009-08-26 14:57 config.ini.template
drwx--x--x 4 open-xchange open-xchange  4096 2009-08-26 16:42 org.eclipse.osgi

Could it be that the groupware has been started with /opt/open-xchange/sbin/open-xchange-groupware instead of the /etc/init.d script?

the 2 directories (and all the files within) were owned by root...

I changed them to be owned by open-xchange - and now the error is no longer occouring...

GUI was loades successfully...

Could it be that the groupware has been started with /opt/open-xchange/sbin/open-xchange-groupware instead of the /etc/init.d script?

Yes...

Okay, glad to hear that it works now. Please keep in mind - if a process or script is launched as root, it writes files for that group/user to the file system. The init.d scripts run as user open-xchange, but the sbin script will run as the user who started it.
