Crawling stops when checking WhoIs

If you're experiencing interruptions during domain checks via WhoIs, it might be due to specific domains or zones. The program may stop scanning when it encounters timeouts or incorrect responses, assuming the WhoIs service is down.

To avoid this issue, try the following:

1. Split Domains into Smaller Batches: Check domains in smaller groups to reduce the load on WhoIs.

2. Review Domain Zones: Some specific domain zones may cause issues. Refer to the provided document listing supported zones to avoid unnecessary stops.
   
   

Following these steps should help minimize interruptions during your checks.
