Fix RuntimeError

✅ Solution

RuntimeError in fluentd, especially with in_forward, often arises from exceeding memory limits when decompressing large compressed data chunks, specifically with zstd. Reduce the `chunk_size_limit` in your source configuration to a smaller value (e.g., 32m, 64m) or disable compression entirely if possible to prevent oversized allocations during decompression, then restart fluentd. You may also consider increasing available system memory.
