Issue

The cache server is down and does not come back even after restart of Tableau Server. The following error might occur in the redis/cacheserver:
"Short read or OOM loading DB. Unrecoverable error, aborting now."
Or
"Fatal error loading the DB: Invalid Argument. Exiting" 

Environment

  • Tableau Server 9 and 10 versions

Resolution

Perform the following in tabadmin:
tabadmin stop
tabadmin clearcache
tabadmin start

This will clear the external cache database and should allow the cache server process to start properly.

Cause

The cache server database has become corrupted or an existing entry is causing problems when the cache server process tries to start.
