  • The REST subsystem in BIG-IP can sometimes suffer from low user space RAM, especially with large configurations. Also there is an upgrade process that occurs immediately after booting into a new version.

    It may help to change Management Provisioning to Large:


    Restjavad can sometimes get into a "stuck" state where the worker processes suffer continuous timeout errors. The log files (/var/log/restjavad*) offer evidence of this behavior: search for the term "timeout" in those files. 

  • Here's the scipt which works at 12.1.3, we do use loginProviderName toms.

    Can you advice where to check "/var/log/restjavad.0.log"?



    response=$(curl -X POST $F5url \

    -H "Content-Type: application/json" \

    -d "{

      \"username\": \"$username\",

      \"password\": \"$password\",

      \"loginProviderName\": \"tmos\"

    }" -k -s)

    echo "Response from server:"

    echo "$response"

  • Are you including "loginProviderName": "tmos" in your POST? Maybe /var/log/restjavad.0.log has some additional info about the failure.
