SOOS supports 3 different DAST Scan Modesbaseline is the default entry for the --scanMode parameter.

SOOS has a scan timeout limit of 180 minutes.  If a scan is not completed in this timeframe the scan will produce an error indicating an incomplete status. The baseline scan mode takes ~2-4 minutes to complete, however Fullscan and APIscan modes are both more complex and will take more time to complete which could end up exceeding 180 minutes depending on the complexity and size (number of pages or endpoints) of the site/API being scanned.

Note that if DAST scans are being run locally it is important to make sure the command window doesn't experience any kind of pause, for example if the screen lock engages. The pause & restart of the command window could cause the scan to exceed the time limit.
