Description
When issuing "mysqladmin debug" on servers with large amounts of memory (eg 128G) the memory counters are incorrect. There are negative numbers, which seem to suggest that some counters are wrapping around.
Eg:
Memory status:
|
Non-mmapped space allocated from system: -824467456
|
Number of free chunks: 970783
|
Number of fastbin blocks: 628
|
Number of mmapped regions: 76
|
Space in mmapped regions: -485408768
|
Maximum total allocated space: 0
|
Space available in freed fastbin blocks: 30304
|
Total allocated space: 879918896
|
Total free space: -1704386352
|
Top-most, releasable space: 10123968
|
Estimated memory (with thread stack): -1265025024
|
Global memory allocated by server: 8696831768
|
Memory allocated by threads: 52050928
