Problem was that log_scrub function did not take required log_sys mutex. Background: Unused space in log blocks are padded with MLOG_DUMMY_RECORD if innodb-scrub-log is enabled. As log files are written on circular fashion old log blocks can be reused later for new redo-log entries. Scrubbing pads unused space in log blocks to avoid visibility of the possible old redo-log contents. log_scrub(): Take log_sys mutex log_pad_current_log_block(): Increase srv_stats.n_log_scrubs if padding is done. srv0srv.cc: Set srv_stats.n_log_scrubs to export vars innodb_scrub_log ha_innodb.cc: Export innodb_scrub_log to global status.
