What could be the possible reason for a 'capacity overflow' error in RisingWave while using the playground setup?

I encountered a 'capacity overflow' error in RisingWave while using the playground setup. The error message was 'thread 'risingwave-main' panicked at 'capacity overflow', library/alloc/src/raw_vec.rs:518:5'. It happened during normal operation, about 20 minutes in, using the official Docker container setup. Could it be related to memory allocation issues?

The 'capacity overflow' error in RisingWave could be due to memory allocation issues, especially when using the playground setup which stores everything in memory.
Increasing the memory of the VM hosting Docker can help prevent such errors.
To avoid OOM errors with large datasets, it is recommended to run RisingWave in a docker compose setup for testing functionalities with relatively large datasets.
