Server is unresponsive and displays an out-of-memory error

1 minute read


The CloudBees Flow server becomes unresponsive and displays an OutOfMemory error prompt that states that the server is out of PermGen space. This prompt occurs when the server is not configured properly for a 64-bit JVM.


Change a setting in wrapper.conf.

  1. Locate the wrapper.conf file.

    • The file to edit on Linux is:

      ` /opt/electriccloud/electriccommander/conf/wrapper.conf`

    • The file to edit on Windows is:

      <CloudBees Flow Automation Platform data dir>/conf/wrapper.conf

    • On Windows 7 or 2008, the DATA_DIRECTORY is typically:

      C:\ProgramData\Electric Cloud\ElectricCommander

  2. Add the following line to the end of the existing “ ” section, being careful to use the next consecutive number.

    In the following example, 7 was the last pre-existing sequence number in this section.

You should set the Java MaxPermSize to a number greater than the default (which is 84m) on an 64-bit CloudBees Flow server (java) installation.
  1. After the file has been edited, restart the server to utilize the new value:

    • On Linux: /etc/init.d/commanderServer restart

    • On Windows: use “Services”
