Bamboo SCP task timeout issue

I'm not sure what changed, but all of a sudden all of my bamboo builds and deployments that have a task for SCP have stopped working. They all generate the below error message. If I go into the OS and manually perform an SCP from the terminal, it works just fine. From bamboo, it hangs for a long time, then fails.

 

Here's the stacktrace:

Hi Joseph,

How long does the transfer take over scp?  One issue could be the timeout in Tomcat:

In the Standalone version, the Tomcat's connectionTimeout value is set to 20000 milliseconds (20 seconds). Depending on your connection speed, if you require to have a connection longer than 20 seconds then you need to increase the value. It's a good idea to consider the geographic location of your users to gauge the suitable length of time.

Please increase the connectionTimeout and see if that helps to resolve the issue.  Try doubling the timeout to 40 seconds or 40000 millilseconds.

See Tomcat's documentation on increasing the timeout.

Cheers,

Branden

Over normal SCP from the Linux Consol, it's less than 10 seconds for the transfer to complete.
