I've been using serviio happily (the pro registered/paid for version) on this setup for some time, always been rock solid, however as of the latest two minor updates, it runs for a while happily, and then stops. I've cranked up the logging and tried to catch the fault. Could anyone please advise on the below?

Thanks

I thought my log level was up to debug, but I Must have set it back to info at some point.

It kind of grinds to a halt slowly.

with debug level logging on , I'm getting told I have java memory heap errors - I can't find where on a freebsd system I can change the Xmx and Xms paramaters though -
I can see it's currently getting invoked with this line

/usr/local/openjdk6/bin/java -Xmx512M -Xms20M -XX:+UseParNewGC -XX:MinHeapFreeRatio=10 -XX:MaxHeapFreeRatio=20 -Djava.net.preferIPv4Stack=true

any suggestions where I might look to edit those paramaters?

What is your Java version?

What is your Java version?

Hi Zip,

thanks for your response.

my java version is openjdk6-b28_3 - which is the up-to-date version on FreeBSD

I also found on this FreeBSD platform where I can edit the size of the java vm memory allocation pool - near the end of the file /usr/local/sbin/serviiod
the default line states

exec java -Xmx512M -Xms20M -XX:+UseParNewGC -XX:MinHeapFreeRatio=10 -XX:MaxHeapFreeRatio=20 $JAVA_OPTS -classpath "$SERVIIO_CLASS_PATH" org.serviio.MediaServer


I tried changing to -Xmx1024M , but I still run into the java heap space errors - I have a lot of data on my media server (about 5tb) - do a lot of people use serviio with big media archives like this (I guess it's not big by some people's standards?) - I changed my library refresh interval from 5 mins to 10 mins, and removed my entire audio folder to see if that took the pressure off, but I still get the errors. they only started happening since recent updates to java and serviio ports on freebsd - could be coincidence though

here's the latest one I spotted in logs

Do you have a folder with a lot of files? It seems to run out of memory when listing files of a folder.

Do you have a folder with a lot of files? It seems to run out of memory when listing files of a folder.

define "a lot" ?

from the below, looks like 16464 files across 1888 subfolders total, 588 gig of films, 3.5 terabytes of tv shows

(tv and films are currently my only 2 folders, I stopped serviio looking at my audio folder to try and reduce the numbers of files/folders involved as a remedy already)

I mean a folder with a lot of items in one level (not folder structure).

OK, I've figured out a command to give me the top (x) folders that have the most items at their one specific level, like you say.

So, it seems the biggest individual one has 189 items in it (half of which are video files, half of which are small text .nfo files)

folder names just invented for your ease of reading , or something of course not real foldernames ...

Anyone?

That looks fine.

Does it happen every time at the same time?

Can you stop Serviio, enable detailed log, remove serviio.log, start Serviio, make it fail and then post the whole log here?

Hello,

Similar issue here, shortly after upgradng to 1.3.1 and Java on a CentOS 6.5 32b ( java.runtime.version=1.6.0_28-b28 ) I'ven noticing that Serviio service does not allow any connection after 24-48hours of being started. Further looking into/opt/serviio/log/derby.log I see the following log:

I do however recall changing the Library refresh interval to 5 minutes and upgrading the Java version to the one shown above. Anyways, I changed the 'library refresh interval' to 10min and went ahead and raised the 'Max Java Heap Size' from 512M to 1024M . This VM I use has 1.5 GB of RAM so 1024M is ok to set as it leaves avail ram for the OS. I made the changes at /opt/serviio/bin/serviio.sh :

#"$JAVA" -Xmx512M -Xms20M -XX:+UseParNewGC -XX:MinHeapFreeRatio=10 -XX:MaxHeapFreeRatio=20 $JAVA_OPTS -classpath "$SERVIIO_CLASS_PATH" org.serviio.MediaServer "$@"
"$JAVA" -Xmx1024M -Xms20M -XX:+UseParNewGC -XX:MinHeapFreeRatio=10 -XX:MaxHeapFreeRatio=20 $JAVA_OPTS -classpath "$SERVIIO_CLASS_PATH" org.serviio.MediaServer "$@"

[root@dlna bin]# ps aux | grep java
serviio 9615 66.6 8.4 1220196 113500 pts/0 Sl 10:49 1:15 java -Xmx1024M -Xms20M -XX:+UseParNewGC -XX:MinHeapFreeRatio=10 -XX:MaxHeapFreeRatio=20 -Djava.net.preferIPv4Stack=true -Djava.awt.headless=true -Dderby.system.home=/opt/serviio/library -Dserviio.home=/opt/serviio -classpath /opt/serviio/lib/*:/opt/serviio/config org.serviio.MediaServer -headless

I will leave it running for a few days and update back if this fixes the prob. Thanks!

Hi,

I have the very same issue with Serviio stopping after about 1 or 2 days with the out of heap memory.

Recently, I have updated to 1.4, before I was running a 1.3.x version and had no issues.

The system is a FreeBSD 8.3 Jail (FreeNAS).
I have also updated the Java package:
openjdk 1.6.0_32
OpenJDK Runtime Environment (build 1.6.0_32-b28)
OpenJDK 64-Bit Server VM (build 23.25-b01, mixed mode)

I tried different refresh intervals (5 - 720 minutes), with and w/o metadata, no online sources,... always hangs after 1 or 2 days.

Please help in resolving this.

Thanks
Marcus

YOu can try to increase the value of Xmx parameter in serviio.sh
