GRIP Deploy Error

I changed the IP of the camera in my pipeline after updating to GRIP 1.3. When I deploy, the status switches to "Running GRIP", but the Network Table Viewer doesn't update values. I checked all settings for the correct team number and can't understand the error I'm getting when I deploy the pipeline:

Re: GRIP Deploy Error

Hey, we are having that same problem. Our grip was working last night and haven't made any changes but now we are having the same problem that you are having. Any help would be appreciated

Re: GRIP Deploy Error

Sounds like some process (possibly a previous instance of GRIP) has a lock on the log file. Can you try running "lsof | grep GRIP.log" on the RIO using SSH?

It also might be a good idea to just remove any previous GRIP.log files just in case.

Yes, our team observed this just before ship too. And as a CSA I wanted to get a handle on the why to confirm the fix. It appears to me that when grip has terminated 100 times that currently it fails starting with this exception, until a remove-all for GRIP.* is issued.

Good luck at the competitions everyone!!

Re: GRIP Deploy Error

I used PuTTY to run that command on the roboRIO. After re-deploying the pipeline GRIP seemed to work. Thanks.

Re: GRIP Deploy Error

Recently I tried to deploy a pipeline to a different robot. After getting the same error on deploy (to the roboRIO), I ran "lsof | grep GRIP.log" with putty (logged in to both lvuser and admin). I still get the same error when I try to deploy.

lsof doesn't fix anything, it just outputs some stuff about open files that should be useful for debugging. What was the output?

Re: GRIP Deploy Error

There is no output. It just goes to a new line.

Re: GRIP Deploy Error

We're getting new errors on deploy...
We commented out this code and pushed:

Code:

table = NetworkTable.getTable("/GRIP/Mar20");

                try {

                        new ProcessBuilder("/home/lvuser/grip1x.log").inheritIO().start();

                } catch (Exception e) {

                        DriverStation.reportError("\n\n\n\nGrip Has Errored!\n\n\n\n", true);

                }

Then we deployed a pipeline that creates a webcam on port 0 (the usb webcam on the robot is "cam0") and publishes the framerate as a number. This is the error message we get when we deploy:

Code:
