Thingworx: Tomcat Related Issue

[mdeshpande-2]

Hello,

I am facing an issue with the tomcat server on which thingworx is deployed. My thingworx instance is handling large amount of data.

Sometimes, my tomcat crashes and I get an error related to java heap space. I lose all the thingworx related data.

I would appreciate any help regarding,What is the issue? Why is it occurring? and how to fix it?

I have attached a snapshot from tomcat logs containing the error, for reference.

Thanks  & Regards,

Madhumita, could you please share you full tomcat log and along with that can you also check if you have nothing defined in the initial memory pool and the Maximum memory pool:

Are you defining max memory for tomcat jvm?

Hello,

Thanks for the help.

I followed the steps in the article. Also, memory pool values were set previously,so I cleared them out. Now Thingworx is working fine.

Thanks & Regards,
