Issue

Trying to import a LAR file (or any other file type) larger than 10MB fails with the following message on the logs:

Unable to parse upload request: UT000020: Connection terminated as request was larger than 10485760

Environment

  • JBoss or Wildfly;
  • Liferay DXP (any version).

Resolution

The maximum allowed size for an HTTP request in JBoss/Wildfly, if not specified is 10MB. In order to be able to upload larger files, you need to explicitly configure the maximum allowed size in a HTTP request.

  1. Open JBoss/Wildfly Console Manager
  2. Go to Configuration: Subsystems > Subsystem: Web/HTTP - Undertow > Settings: HTTP;
  3. Under HTTP Listener, locate the option Max post size;
  4. Increase the value to the maximum size in bytes you expect your server to accept (1073741824 for 1GB);
  5. Save and restart JBoss/Wildfly.
