Symptoms:

This error may be seen in Junos Space logs:

Workaround:

Modify the following values from 1073741824 to 1536000000 in the file /etc/httpd/conf.d/mod_security.conf.
  1. Check the current values:

    grep "SecRequestBodyLimit\|SecRequestBodyNoFilesLimit\|SecRequestBodyInMemoryLimit" /etc/httpd/conf.d/mod_security.conf

    SecRequestBodyLimit 1073741824
    SecRequestBodyNoFilesLimit 1073741824
    SecRequestBodyInMemoryLimit 1073741824


    If the values listed above are smaller than 1536000000 please continue.
  2. Backup current config file:

    cp /etc/httpd/conf.d/mod_security.conf /home/admin/http_mod_security.conf.old
  3. Update values:

    sed -i 's/1073741824/1536000000/' /etc/httpd/conf.d/mod_security.conf
  4. Confirm Values are modified:

    grep "SecRequestBodyLimit\|SecRequestBodyNoFilesLimit\|SecRequestBodyInMemoryLimit" /etc/httpd/conf.d/mod_security.conf
