| Doc Text: |
Due to a low default entry cache size value, the Directory Server database had to resolve many deadlocks during resource-intensive tasks. In certain situations, this could result in a "DB PANIC" error and the server no longer responded to requests. After the server was restarted, Directory Server started with a delay to recover the database. However, this recovery could fail, and the database could corrupt. This patch increases the default entry cache size in the nsslapd-cachememsize parameter to 200 MB. As a result, out-of-lock situations or "DB PANIC" errors no longer occur in the mentioned scenario.
