Execution timeout	Set execution timeout to determine how long workflows can run.	howto

Setting execution timeouts

A workflow times out and gets canceled after this time (in seconds). If the workflow runs in the main process, a soft timeout happens (takes effect after the current node finishes). If a workflow runs in its own process, n8n attempts a soft timeout first, then kills the process after waiting for a fifth of the given timeout duration.

EXECUTIONS_TIMEOUT default is -1. For example, if you want to set the timeout to one hour:

export EXECUTIONS_TIMEOUT=3600

You can also set maximum execution time (in seconds) for each workflow individually. For example, if you want to set maximum execution time to two hours:

export EXECUTIONS_TIMEOUT_MAX=7200

Refer to Environment variables reference for more information on each variable.
