What would be the possible reason for this error message.
Advice and help requested
Thanks

Hello,

the most likely reason is that your Tomcat has not been assigned enough heap memory and is struggling to free memory when new data is to be loaded into it. Depending on how much memory is needed, you can either run into a "GC overhead limit", which means it has taken Java too long to attempt to free up enough memory, or "Java heap space" when there just isn't enough memory available or that can be freed.

What are your memory settings for your Alfresco Repository?

Axel
