0-5 - Cache file size exceeded

Other modules reuse the file-based caching mechanism of the Common layer (currently the metadata module), and the file caching mechanism of the Common layer has “detected” that the file size has exceeded the limit.

Possible Causes

1. The user has improperly configured the Java System Property (configured with -D) dubbo.mapping.cache.maxFileSize or dubbo.meta.cache.maxFileSize.
2. The cache file has been corrupted due to a file system or disk error.

dubbo.mapping.cache.maxFileSize and dubbo.meta.cache.maxFileSize do not have explicitly stated default values, while the maximum file size default value found based on the logic of org.apache.dubbo.common.cache.FileCacheStore.LimitedLengthBufferedWriter is: Long.MAX_VALUE (2⁶³-1) .

Troubleshooting and Resolution Steps

1. Try reconfiguring the above Java System Property (configured with -D).
2. Delete the cache folder and restart Provider and Consumer (the cache folder is generally located in ~/.dubbo. If dubbo.meta.cache.filePath and dubbo.mapping.cache.filePath are configured, then the path will be that).
3. If these System Properties are indeed not configured, please issue a problem on the GitHub Issue Tracker.
