Shiny-server Error

[Abdur Rehman Raja]

Hi,

I keep receiving this error, everytime I try to start my shiny app:

-bash: line 1: 2026 Killed R --no-save --slave -f \/opt\/shiny-server\/R\/SockJSAdapter\.R

I have 3 other apps that work perfectly fine on the server. My app works when I run it locally, but outputs this error when I upload on the server. Any help would be appreciated.

Thanks, 

Abdur

Where do you see this error? Right in the browser?

Can you send along the contents of /var/log/shiny-server.log and anything relevant in /var/log/shiny-server/*.log?

I have a similar problem with the Shiny sever on a micro EC2 instance. 

The chrome browser throws a JS error with the following error in the console: 

Loading required package: NLP

-su: line 1:  1637 Killed                  R --no-save --slave -f \/opt\/shiny-server\/R\/SockJSAdapter\.R

The contents of /var/log/shiny-server.log is the same as above.

The contents of my config file is the following:

# Instruct Shiny Server to run applications as the user "shiny"

run_as shiny;

# Define a server that listens on port 3838

server {

listen 3838;

# Define a location at the base URL

location / {

# Host the directory of Shiny Apps stored in this directory

site_dir /var/shiny-server/www;

# Log all Shiny output to files in this directory

log_dir /var/log/shiny-server;

# When a user visits the base URL rather than a particular application,

# an index of the applications available in this directory will be shown.

directory_index off;

app_init_timeout 250;

}

}

Any one else run into a similar problem?

Thanks

Sounds like you might be running out of memory. You can type dmesg to see the kernel log, if it's memory you should see something like "Out of memory: Killed process nnn".

For me it was a memory issue, try increasing your memory. If that doesn't work try increasing the app_init_timeout. Its possible that your app is taking too long to load and after the set time it kills the app.

Yup it was a memory issue.

Increasing the size of the instance solved the problem.

Thanks!
