Java Heap Space Error in Batch Run

kumaralp

Hi Narayan,

I am scheduling about 150 sahi scripts in batch mode.
Getting java heap space error after every 48 - 50 sahi scripts run.

Also I have edited sahi.bat -

java -Xms128m -Xmx128m -classpath %SAHI_EXT_CLASS_PATH%;%SAHI_CLASS_PATH% net.sf.sahi.Proxy "%SAHI_HOME%" "%SAHI_USERDATA_DIR_TMP%"

Kindly suggest any solution.

Hi kumaralp,

You could increase the memory further. Generally Sahi does not need that much memory. It could be some particular script that is causing the problem.

Hi Narayan,

I have increased memory to 512, but still after 47 - 50 scripts, error comes both in Firefox and Chrome.

I have noticed that after every script is run memory usage increases.

Following is the log of the error -

Hi Narayan,

We are still facing the following issues: -

1. JVM is not picking up the parameters which I had set in sahi.bat
2. The heap usage increase with more and more scripts running

Can u please suggest a solution for these issues. I have logged my observations for the second issue in an excel if required I will forward you this document.

narayan

Hi kumaralp,

1) You will have to specify how you are passing the parameters. What is the current heapsize?
2) In your scripts are you storing something in memory or declaring large variables in the global scope?

It would be good if you emailed the excel sheet to support@sahi.co.in

Regards,
Narayan

Hi Narayan,

I have emailed Files.zip which contains

1. sahi.bat.txt
2. There is one Folder Script Example which contains a script along with required code files
3. Also sahimonitor.csv in which memory usage is given during batch run
