Hi,
I have been using Tomcat6.1( running on windows ) for an application that has
been connecting to Infor ERP LN ( formerly BaaN ).
It is given with a webapp which was installed on Tomcat and that's the way it
connects to ERPLN from Tomcat.
This is setup running fine ( for 2 years now, no hassels ). As a new
requirement we developed another application relying on the same architecture.
In this app we have voluminous data. So, we faced issues like "time-out
exception" which was increased in server.xml as mentioned below.
<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="900000000"
redirectPort="8443" maxPostSize="0"/>
Later we ran in OutOfMemory Exception. So I increased the memory pool sizes as
shown below.
Initital memory Pool - 1024 MB
Maximum memory Pool - 1024 MB
Now that after increasing the above the error was gone. But after few requests
it comes back. Since request and response sizes are about 2MB( which are usual
in ERP scenarios ). The error is as below.
Exception in thread "ContainerBackgroundProcessor[StandardEngine[Catalina]]"
java.lang.OutOfMemoryError: Java heap space
java.util.logging.ErrorManager: 1
java.lang.NullPointerException
at org.apache.juli.FileHandler.publish(FileHandler.java:136)
Exception in thread "http-8080-2" java.lang.OutOfMemoryError: Java heap space
The memory size of process has hit high and doesn't come down at all.
Mem Usage - 137,700 K
Peak Mem Usage - 784,644 K
VM Size - 1,076,804
The above is on windows machine.
Can you please suggest how to resolve the issue?
Regards,
Ramprasad
