REST Call Timeout - Python SDK

Running 11.6.0 HF5 the following Python SDK call:

 

mgmt.tm.util.bash.exec_cmd(
    command='run',
    utilCmdArgs="-c 'tmsh save /sys ucs /var/local/ucs/f5-create-backup-python.ucs'",
)

 

...throws this exception:

 

Traceback (most recent call last):

        "at java.util.TimerThread.run(Timer.java:505)\\n"
    ]
}'

 

I'm using util.bash to make the call because of the old TMOS version. This same script works fine on our other 11.6.0 LTMs - two of them are failing and under much heavier load.

Is there a way to increase this timeout?

    I use this method to increase the timeout using the REST API, so you may be able to translate it for the SDK. (sorry Python SDK isn't my strong point)

     

    curl -X POST \
  'https://bigip1.local/mgmt/shared/authn/login' \
  -H 'Cache-Control: no-cache' \
  -H 'Content-Type: application/json' \
  -d '{
    "username":"admin",
    "password":"admin",
    "loginProviderName": "tmos"
}'

     

    This will respond with a JSON body containing a token (token.token) Use this token on a second request to extend your timeout. If your token was ABCDEFGHIJKMLNOPQRSTUVWXYZ, your second request would look like this:

     

    curl -X PATCH \
  https://bigip1.local/mgmt/shared/authz/tokens/ABCDEFGHIJKMLNOPQRSTUVWXYZ \
  -H 'Cache-Control: no-cache' \
  -H 'Content-Type: application/json' \
  -d '{
    "timeout":"36000"
}'
