Throttling Limit Reached, Stopping Migration
This is expected behavior - your migration will automatically resume.
Error Message
Migration Status
Throttling limit reached, stopping migration
This message indicates the migration has been temporarily paused due to rate limiting and will automatically resume.
Automatic Throttle Recovery
Causes
Cause 1: Google IMAP Limitations
Google imposes download restrictions on IMAP connections. Google allows a download of between 2.5 and 3.5 GB of data per day, after which accounts may be disabled for up to 24 hours.
Auto-Recovery: Cloudiway automatically pauses migrations upon reaching this threshold and restarts them 18 hours later.
Cause 2: Low Throughput Detection
When fewer than 250 items migrate within an hour across any connector type, the system identifies this as throttling behavior.
Auto-Recovery: The platform automatically pauses for 4 hours before resuming.
Cause 3: Consecutive Timeouts
Multiple failed connection attempts trigger automatic throttling detection, causing the platform to pause and reschedule the migration.
Auto-Recovery: Migration is automatically rescheduled and will resume without intervention.
Resolution
No Action Required
This is expected behavior requiring no manual intervention. Pending migrations automatically restart without user action.
