I remember reading somewhere (can't forget where, and I may be
incorrect) that when available, sbrk is a more reliable indication of
memory use for squid than mallinfo(). However, I'm seeing this on a box;
Process Data Segment Size via sbrk(): 1040844 KB
Maximum Resident Size: 0 KB
Page faults with physical i/o: 0
Memory usage for squid via mallinfo():
Total space in arena: 1621452 KB
Ordinary blocks: 1620888 KB 8820 blks
Small blocks: 0 KB 0 blks
Holding blocks: 20928 KB 4 blks
Free Small blocks: 0 KB
Free Ordinary blocks: 563 KB
Total in use: 1641816 KB 100%
Total free: 563 KB 0%
Total size: 1642380 KB
Memory accounted for:
Total accounted: 1565651 KB
As you can see, sbrk() is considerably less than total size via
mallinfo(). Is this unusual? Any thoughts about which is better, if
both are available?
Thanks,
