[NFS-Ganesha-Devel] [S] Change in ...nfs-ganesha[next]: main: periodically poke malloc()/free() to release memory

Kaleb KEITHLEY has uploaded this change for review. ( https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/1170254?usp=email ) Change subject: main: periodically poke malloc()/free() to release memory ...................................................................... main: periodically poke malloc()/free() to release memory Try to improve the odds that freed memory will be released to the operating system, potentially reducing VIRT and RES sizes. malloc_trim(3) is in glibc, and when compiling with tcmalloc or jemalloc it effectively becomes a no-op. For allocations above a certain size (128K default) malloc(3) uses mmap, which should usually be released when freed. But below that memory is allocated by the use of brk(2) to increase the size of the program in memory. Freeing memory allocated with brk(2) may or may not happen automatically. Calling malloc_trim(2) may release memory when it isn't released after freeing it. Change-Id: I543e320128db8f6382c462a1b52518a89a0bcfcb Signed-off-by: Kaleb S.
