Error description

  • The server startup is slowed down and hung threads appear in the
    logs due to a large amount of searchable business data.
    This problem is more frequent as more snapshots are deployed.
    The initial load of the BusinessDataAliasCache loops over
    branches, versions, projects, and snapshots to load all BPDs to
    extract information to store in the BusinessDataAliascache.
