Failed to commit buffered response

[Simona]

Hello, I'm Simona and I'm new to this forum.

I've been experiencing some issues with Alfresco 7, which was installed in 2021. Until a few days ago, it was working fine, but now it freezes after about an hour of running, and this error appears in the logs:

2025-01-29 09:36:11,510 WARN [cache.node.nodesTransactionalCache] [DefaultScheduler_Worker-1] Transactional update cache 'org.alfresco.cache.node.nodesTransactionalCache' is full (250000).

Can anyone help me? If needed, I can also post the configuration files.

Thank you very much.

Hi Simona,

Can you check Tomcat or Proxy Configuration: If you're using a reverse proxy (like Nginx), ensure that the proxy settings are correctly configured to handle larger requests and responses. You might need to adjust the buffer sizes and timeouts in the proxy server configuration.

You could start by reviewing Tomcat logs (catalina.out) and Alfresco logs for more detailed errors or stack traces.

Hi,

thanks a lot for your reply. There is no proxy; Tomcat is called directly.
I noticed an unusual pattern in the Java heap memory usage of Alfresco's Tomcat. It seems that memory usage keeps increasing without ever being released, and every half hour, this increase becomes more noticeable. Is there a way to understand why it is never freed?
