Out of curiosity..
everytime cyrus needs to mmap/munmap something. it uses its mmap
encapsulation, which is map_refresh and map_free.
So every once in a while I get this on strace.
14:27:02.148097 munmap(0x54968000, 373915648) = 0
14:27:02.148765 mmap2(NULL, 373932032, PROT_READ, MAP_SHARED, 8, 0) =
which is a map_free followed by a map_refresh.
14:27:31.041808 mmap2(NULL, 4096, PROT_READ|PROT_WRITE,
MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x54963000
14:27:31.042150 munmap(0x54963000, 4096) = 0
Happens way much more. Its not cyrus doing it directly because its not
going through it's mmap encapsulation, so it can only be some lib used
What is it ?
