Severity: 4-Minor


When viewing statistics for snapshot files, tmctl leaks a small amount of memory and displays the message: tmctl: BUG: tmstat_dealloc invoked on a handle with rows outstanding; release all rows before calling tmstat_dealloc at <address>


Errors written to output when running tmctl. The leak itself is very small and is only for tmctl (i.e., it does not have a cumulative, detrimental effect on the system that a TMM or MCP leak might).


Using tmctl to view statistics of snapshot files, for example: tmctl -D /shared/tmstat/snapshots memory_usage_stat -s time,name,allocated,max_allocated name=access



Fix Information

This issue no longer occurs when using tmctl to view statistics for snapshot files.
