This was running fine. I changed the start command today from --innodb-buffer-pool-size=1G to --innodb-buffer-pool-size=128M. Now it crashes after startup - I've tried restarting and redeploying with no luck. I also tried reverting the change and it still crashes. I did this in another environment (which sees more traffic) and it's fine. The error I'm seeing in the logs doesn't look like it's related but I could be wrong:

Are you upgrading the version of mysql ? if yes , try using the same version of mysql which you are using before , this issue occurred to me when I upgraded as it is without proper migration

I did upgrade but I thought it had completed successfully before I made the config change so I didn't mention it. There was deployment problems at the time so I guess it hadn't happened. Reverted to previous version and it looks like it's ok. Thanks.
