Fact

Nordic Edge Automatic Account Manager 3

Situation

Automatic Account Manager stops running policies with error:

• “Exception in thread “Timer-0” java.lang.OutOfMemoryError” reported in aamlog.txt/aamstudiolog.txt.

or

• “Caused by: java.lang.OutOfMemoryError: PermGen space” reported in aamstudiolog.txt

Solution

The AAM Java-process has reached the memory limit.

For error “Exception in thread “Timer-0” java.lang.OutOfMemoryError”, edit AAMService.lax and/or AAMStudio.lax and modify lax.nl.java.option.java.heap.size.max

• Set max size to 1,5 GB of memory

lax.nl.java.option.java.heap.size.max=1610612736

• Set max size 2 GB of memory

lax.nl.java.option.java.heap.size.max=2147483648

• Set max size to 4 GB of memory

lax.nl.java.option.java.heap.size.max=4294967296

For error “Caused by: java.lang.OutOfMemoryError: PermGen space”, edit AAMService .lax and/or AAMStudio.lax and add the following parameter after parameter lax.nl.java.option.java.heap.size.max

#   LAX.NL.JAVA.OPTION.ADDITIONAL
#   -------------------------------------
#   The default MaxPermSize is 64GB.
lax.nl.java.option.additional=-XX:MaxPermSize=128m

Restart the AAMService/AAMStudio.

NOTE: The 32-bit process model limits memory addressing to 4GB. In practice, this limit is even lower on some operating systems. For a 32-bit java process running on Windows 64bit, the maximum of the java heap size is <2GB (2047MB). On Windows 32bit, the maximum is 1,4GB. 

The maximum heap size is determined by the maximum amount of contiguous memory space that the Java process can allocate. On a Windows 64bit computer with <=4GB RAM the operating system itself may allocate most of the resources which decreases the maximum amount of contigous memory space available. For example: A Windows 64bit computer with 4GB RAM and a java heap size of 2047 MB may run out of memory before the java heap exceeds 2047 MB.  A Windows 64bit computer with 8GB RAM and a java heap size of 4GB will not run out of memory before the java heap exceeds 4GB.
