H2 database connection issue after a time since 3.78.1

post by Alexander_von_Rockenthien on Mar 14, 2025

Hello,

I recently installed Nexus version 3.71.0 on a Linux system. Everything was working fine until I updated to 3.78.1.

Since then, after a certain period of time, I’ve been experiencing H2 database connection errors.

At that point, access to the UI is no longer possible.

Cause: java.sql.SQLTransientConnectionException: nexus - Connection is not available, request timed out after 30000ms.
