Hi,I'm experiencing an 'out of memory' error in an Alfresco Web Service for uploading documents. The process creates one folder per hour and uploads the documents into them, acording with the time of uploading.The memory taken by the service increases little by little and after 5 hours running and w

Have you checked this link?
http://wiki.alfresco.com/wiki/JVM_Tuning

There might be some other cause.
And also if you monitor the Alfresco classes as well it will be more informative.

Hi Mits,

These are my JVM settings:

# Server Hotspot VM
JAVA_OPTS="$JAVA_OPTS -server"
# Modelo de datos de x bits -d32/-d64
JAVA_OPTS="$JAVA_OPTS -d64"
# Heap Size - Total old generation
JAVA_OPTS="$JAVA_OPTS -Xms1024m -Xmx1024m"
# Total permanent generation
JAVA_OPTS="$JAVA_OPTS -XX : PermSize=192m"

JAVA_OPTS="$JAVA_OPTS -server -Xss256k -XX :MaxPermSize=256m -XX :NewSize=512m -XX :ReservedCodeCacheSize=128m"

# CONFIGURACION GARBAGE COLLECTOR
JAVA_OPTS="${JAVA_OPTS} -XX :+UseConcMarkSweepGC"
JAVA_OPTS="${JAVA_OPTS} -XX :+CMSIncrementalMode"
JAVA_OPTS="${JAVA_OPTS} -XX :CMSInitiatingOccupancyFraction=80"

I've checked the parameters with de wiki article that you provided and seem to be correct.
Besides here is a Eclipse-MAT report showing the objects contained in the heap dump:

The first image shows the objects without grouping:

The second one shows the objects grouped by class:

Aparently, org.springframework.beans.factory.support.DefaultListableBeanFactory classes are consuming a great amount of memory.
What can be causing this?

Thanks for the help.

Hi,

Hi,

Any ideas about this problem?

I also tried installing my project AMP in Alfresco 4.1.2 war, just to discard it could be related with my current version, but the results were the same.

Thanks in advance.
