Cron job error with /usr/local/cpanel/scripts/update_db_cache

[Adrianne]

I have a new dedicated server setup with root access and have still been receiving the following email alerts every 12hrs:

Subject:
Cron <root@****> /usr/bin/test -x /usr/local/cpanel/scripts/update_db_cache && /usr/local/cpanel/scripts/update_db_cache

Message:

Cpanel::Exception/(XID g4es8v) The system failed to load and to parse the file “/var/cpanel/databases/dbindex.db.json” because of an error: (XID gpzbmk) The system failed to parse the JSON stream for the caller “(eval)” because of an error: malformed JSON string, neither tag, array, object, number, string or atom, at character offset 2 (before "(end of string)") at /usr/local/cpanel/Cpanel/JSON.pm line 108.

Any insight on how I may be able to fix this error and prevent the cron from failing and stop receiving these messages would be greatly appreciated.

Hello

It's possible the "/var/cpanel/databases/dbindex.db.json" file is corrupt. Please let us know if the following commands help to address the issue:

mv /var/cpanel/databases/dbindex.db.json /root/
/usr/local/cpanel/bin/dbindex

Thank you.
