Hi,
Are you seeing any long GC related error in “terracotta-server.log” file? Also this NonStopCache exception is usually thrown when there is less timeout setting configured in cache configuration file. You can update the fine tune the below timeout setting in cache configuration file.

<nonstop immediateTimeout="true"
timeoutMillis="45000"/>

Thanks,
Yogesh

Can you let me know what does GC mean,also where is the cache configuration file location,I am new to terracotta,so I am not sure what they are referring to.

Hi Barney/Elsa,

GC stands for GarbageCollection, internally used by the JVM to clean up unused objects and freeing heap space for new objects.
You will have to introspect your installation directory where Terracotta is installed to find this cache configuration file.

I myself have never worked with Terracotta.

Here is the path for Cache configuration file in Integrations server.

<INSTALL_DIR>/IntegrationServer/instances/default/config/Caching/
