Unable to Upload file into the Document & Media when size is more then 10 mb

Issue

• When a user is trying to upload the file into the document and media, it does not upload when the size is more than 10 MB.

Environment

• Liferay DXP 7.1
• Liferay DXP 7.2
• JBoss

Resolution

• Increasemax-post-size (10485760 = 10 MB by default) on the listeners in the undertow subsystem to accept large file post requests.
  • For example, setting max-post-size to 31457280 (= 30MB) in standalone.xml file {Jboss_home}/standalone→ configuration→standalone.xml
    

    <subsystem xmlns="urn:jboss:domain:undertow:3.1">
    <buffer-cache name="default"/>
    <server name="default-server">
    <ajp-listener name="ajp" max-post-size="31457280" socket-binding="ajp"/>
    <http-listener name="default" max-post-size="31457280" socket-binding="http" redirect-socket="https"/>
    <https-listener name="https" max-post-size="31457280" socket-binding="https" security-realm="ApplicationRealm"/>
    ...
    </server>
    ...
