Visitation model - "Cannot allocate memory" error

[rpi]

Hi,

I am running the visitation model and I get an error: Cannot allocate memory. Below is the log file. Yesterday I managed to run with the same files and grid. Can you please advice me on how to solve this?

Thank you for your help

Hello @rpi,

Thank you for writing in to the Forums with your question.

Did you change any of the model inputs in any way since your previous, successful run? Your log file shows “ERROR Something went wrong when adding task photo-user-day [PUD]-calculation”. PUD calculations are computed on a remote server. Consequently, this model requires a connection to the internet. Is there a chance you were not connected or that your connection was interrupted?

Hi Jesse,

Thank you for your reply.
No, all the files are the same from yesterday. I also tried with the sample data for the recreation model just to check the internet connection and it seems to work well.

Interestingly, I tried running the the recreation model with the sample data and even then this error was happening! So THANK YOU @rpi for letting us know about this.

I just restarted the recreation server. Could you try running the model again on your data to see if it’s working for you? It’s working again for the sample data, so it might be good to go for your study area as well.

Hi James,

Yes the model is working again!
Thank you for your help!

Thank you @jdouglass ! I should have tried running the sample data earlier. I’m glad it’s working for everyone now!
