Purging a large amount of content may cause the server to crash

[CodeZhangBorui]

When I use the Purge command to clean a large amount of content (e.g., over ten thousand entries), Ledger causes the server's main thread to block and eventually triggers the server Watchdog to force the server to crash.

Although it might be possible to try disabling the server Watchdog to solve this problem, I actually hope that Ledger can process or batch process on another thread to prevent the server from freezing.

Expected behavior

Execute the Purge command normally.

Observed/actual behavior

The server froze and then crashes due to watchdog.

For more information, see [Other].

Steps/models to reproduce

1. Normally start the server
2. Try executing a massive Purge command (e.g. /ledger purge source:@gravity before:3d)
3. The server initially observed a severe drop in TPS, and then (after ~10s) completely froze.
4. Triggering Watchdog timeout, server crashes
