Full text search host restarts repeatedly under Linux (SQL Server 2019 rc 1)
Under Linux, after enabling full text search in a table and during the population of the index, one sees frequent messages in the log
Error '0x80004005' occurred during full-text index population for table or indexed view 'mytable' (table or indexed view ID '629173587', database ID '5'), full-text key value '5567999'. Attempt will be made to reindex it.
In the errorlog there are many repeated messages like
The fulltext filter daemon host (FDHost) process has stopped abnormally. This can occur if an incorrectly configured or malfunctioning linguistic component, such as a wordbreaker, stemmer or filter has caused an irrecoverable error during full-text indexing or query processing. The process will be restarted automatically.
And the sql server was even restarted.
As a workaround, we set the full text service timeout to double than the default, 120 seconds
spfulltextservice 'ft_timeout', 120000
This improved the service, but the logs are still filling with messages after adding records.
This is also happening with me using SQL Server 2017 on Windows Server 2016. I'm only indexing standard datatype columns (varchar, nvarchar), not documents, so I don't understand why timeouts would occur.
