【问题描述】（请对问题进行描述，方便定位问题）

At line 340, there is a call to addCacheForDBHandler. When addCacheForDBHandler returns an error (err), this error is handled, and dbHandler.Close() is called. However, dbHandler is nil when err is not nil, causing a panic.

Modifying the node configuration storage.state_cache_config.hard_max_cache_size in chainmaker.yml to a value less than 0 can trigger this issue.
