The default Resource Expiration Timeout for the WPS service is 300 seconds (5 minutes). This time period is too short: there may be a high cost for loosing a resource from lengthy WPS execution by not replying quickly enough. For example, when exporting a GeoPackage. This value should be increased to 1 hour (at least).
To see/change this value in in the web administration interface, see: Services > WPS > Resource Settings
