UMS on linux (manjaro) crash / breaks off

[newbietux]

Hello UMS-community,

I'd use various UMS versions a long time with various linux distributions.
Since 1 month the UMS server crashed after a short time.

I tested with various versions from 10.21.1, 11.4.0, 13.3.0, 13.8.1 and 14.0.2 - overall the same. After a short time the server go down.

For the supporter to know:
All the years I use a option in UMS.sh to use a separate directory to find and store all files (database, UMS.conf, and so on):

Code: Select all

UMS_PROFILE="/opt/ums-etc/UMS.conf"
export UMS_PROFILE

This is written on line 6, after the "DIRNAME"-option.

What ist the problem?

I had a quick look at those logs but did not see any errors or anything that looks odd, at least from UMS's perspective.

I know next to nothing about Linux though so the pid logs made no sense to me. Maybe @Boss has an idea?

It would be helpful if you could post your full logs (see the section in red above) so it includes all your configuration settings too.

Hello @mik_s,

many thanks for the support for my not alldayly problem with linux system.

My linux is manjaro with kernel 6.8.12-3 and kde 5 plasma 6 desktop with wayland.

Tonight I started only UMS version V.14.0.2. After setting log_level=TRACE I started the UMS server with the graphical java UI. Then I touch the button "Server restart". After the crash I zipped the ordinary logfile and the core-dump (hs_err_pid...) from the UMS application folder. These core-dump where written whenever a crash occurs and shows many details about the system and environment.

I hope @Boss or other linux experts have a idea about the reason for the crashs.

Do you know if UMS is using your system java or java which came with UMS?
If you are not sure, paste the text from the file UMS.sh from your UMS folder.

[newbietux]

The following code are from UMS.sh and should be related to java:

Code: Select all

# Setup the JVM
if [ -z "$JAVA" ]; then
    if [ -z "$JAVA_HOME" ]; then
        JAVA="java"
    else
        JAVA="$JAVA_HOME/bin/java"
    fi
fi

# Use our JVM if it exists
if [ -f jre17/bin/java ]; then
    JAVA="jre17/bin/java"
fi

# Setup the classpath
# since we always cd to the working dir, these a) can be unqualified and b) *must*
# be unqualified: https://code.google.com/p/ps3mediaserver/issues/detail?id=1122
PMS_JARS="update.jar:ums.jar"

The core dump file - they are written from java to the UMS-bin-folder started with many infos about java.
So I think that UMS use the java-vm from within the UMS-tree.
Besides that the software center shows that OpenJDK 17 ist not installed rather Version 21 ist installed.

If I test in the shell with

Code: Select all

echo "$JAVA"
echo "$JAVA_HOME"

no output where written.

If you comment out the following like this:

# Use our JVM if it exists
#if [ -f jre17/bin/java ]; then
# JAVA="jre17/bin/java"
#fi

UMS should use your system Java.
That would be the first thing I would try.

Hello @Boss,
many thanks for the first help.

Now UMS not crashes or break off, but it have a network problem.
Today it's a little late and so I test today in the evening. I give response if I find out more.

[newbietux]

I configured on the graphical ui the network new and now it is all right and the smart-tv can access to UMS and play the video.
Now I may looking for the sorting config, because these is not as before - it's not straight alphabetical.

Why this is so I looking today evening.

[boss]

I normally edit UMS.conf directly to change settings.
But through the UMS GUI: UMS-IP:9001/settings
Then goto:
Navigation Settings
File sorting/naming
File order

There you can configure UMS to sort to different criteria.
In UMS's default setting, it should be on "Alphanumeric"
If not, change that setting to "Alphanumeric"
The next setting is: Ignore articles "a" and "the" while sorting,
This ignores "a" and "the" when sorting.
EG: A file named "a good day" will come after a file named "badlands"
If you do not want the sorting like that and want to include the "a" and "and" in the sorting order, untick that option.
Cheers
