The steps for troubleshooting crash issues are as follows:
- Simulate the crash using the DEBUG SEGFAULT command:
$ bin/redis-cli DEBUG SEGFAULT Error: Server closed the connection
- Check the log of the Redis instance after it crashes:
=== REDIS BUG REPORT START: Cut & paste starting from here ===
