How to fix “bitnami mongodb failed to refresh key cache” error?

Bitnami offers software packages making setup and administration simple. When this error occurs, It may be due to different problems. Debugging it could involve some research. We can use the following steps to fix the issue:

1. Lack of disk space is one of the most frequent causes of key cache refresh failures. There should be enough disk space in order to carry out tasks like refreshing the key cache. So, verify that there is enough free disk space on the server where MongoDB is operating for MongoDB to function without any problems.

2. Verify that MongoDB is authorized to build and update cache files. So, access to and modification of the folders containing the key cache files should be permitted to the person operating the server.

3. If the file system is malfunctioning or if another process has locked the key cache files, MongoDB can have troubles. While MongoDB is operating, also, make sure that these files are closed and see whether any other processes or programs are accessing them.

4. In order to find whether any particular cache-related settings are the source of the problems, review the MongoDB setup settings. Make sure the cache settings are suitable for the resources on the system by checking the MongoDB setup file.

5. The key cache files are susceptible to corruption. In some situations, we have to remove the current cache files, as MongoDB will recreate them upon restarting.

6. Make sure that the version of MongoDB we are using is compatible with the Bitnami MongoDB setup. A more recent version of MongoDB might not be completely compatible with the Bitnami stack, which could cause unanticipated problems.

7. Lastly, in the event that the system is short on memory or other resources, MongoDB’s key cache refresh may fail. So, ensure that the server has enough RAM to support MongoDB’s resource requirements, particularly if we’re working with big datasets.
