After several hours of work, I observe the following message in the logs:

The question is how to increase the heap space?

    1 answer 1

    To understand which of the options you need to "twist" I recommend a good article on Habré: What types of OutOfMemoryError are there or what parts does java process memory consist of

    So to eliminate Java heap space you need to tyunit -Xms and -Xmx

    Next comes the next question: how to do it in JBoss ? It depends on how you run it. For example, if by a script, for example, like this:

     /opt/jboss-as/bin/standalone.sh

    That option (at least) two:

    • specify the necessary options on the command line: JAVA_OPTS='-Xmx512m' /opt/jboss-as/bin/standalone.sh
    • set JAVA_OPTS in the configuration file ( /opt/jboss-as/bin/standalone.conf in my case)

    PS And Spring nothing to do with it.
