Tika timeout was reached message
The message Timeout was reached, Tika PID = 0 in the server log indicates that Tika could not complete processing of an attachment due to its size.
By default, Tika processing of an attachment times out after 10 seconds. To increase the timeout limit to allow for processing of larger attachments, use the notes.ini setting DEBUG_TIKA_TIMEOUT=<value in milliseconds>. For example, to increase the timeout to 20 seconds, use DEBUG_TIKA_TIMEOUT=20000.
Alternatively, limit the size of attachments that can be full-text searched as described in Configuring the attachment types that can be full-text indexed.
