Issue
- External connections getting dropped on Liferay PaaS environment with
java.net.BindException error.
Environment
- Liferay 7.0
- Liferay 7.1
- Liferay 7.2
- Liferay 7.3
Resolution
- There is a limitation of Liferay PaaS, connections from the project environment to external endpoints use a NAT solution with a 120-second timeout per connection. New connections created successively in a short period of time can lead to port exhaustion and dropped outbound traffic.
-
Connection pooling can prevent this problem.
