The numbers shown for memory usage also include shared memory, ie memory used by multiple processes/threads, these shared areas will be counted multiple times.
Use `free` to find the real amount of used memory on your server (look at the +/- buffers section)

Subject: [Users] regarding memory usage
Hi______________________________________________________________________
1. Is there any benefit of increasing the value of PKG_MEM_POOL_SIZE and SHM_MEM_SIZE ?
/*used only if PKG_MALLOC is defined*/
#define PKG_MEM_POOL_SIZE 1024*1024
/*used if SH_MEM is defined*/
#define SHM_MEM_SIZE 32
2. I've compiled my ser with
#define PKG_MEM_POOL_SIZE 1024*1024*512
ans started using ser -m 100 option with children=4 and listening on two ips
when I started memory usages was seems to fine for few days(3-4) less then 1GB but after that nealy 1.7 - 1.8 GB of memory usage and when I do top:
16165 root 15 0 617m 54m 36m S 0.3 2.7 0:16.34 ser
16167 root 15 0 617m 54m 36m S 0.3 2.7 0:15.89 ser
16164 root 15 0 617m 54m 36m S 0.3 2.7 0:16.29 ser
16166 root 15 0 617m 54m 36m S 0.7 2.7 0:16.16 ser
16172 root 16 0 617m 53m 35m S 0.0 2.7 0:05.04 ser
16168 root 16 0 617m 52m 34m S 0.0 2.6 0:00.09 ser
16170 root 16 0 617m 52m 34m S 0.0 2.6 0:00.07 ser
16169 root 16 0 617m 52m 34m S 0.0 2.6 0:00.08 ser
16171 root 16 0 617m 52m 34m S 0.0 2.6 0:00.10 ser
16163 root 16 0 617m 52m 34m S 0.0 2.6 0:00.01 ser
16145 root 25 0 617m 52m 34m S 0.0 2.6 0:07.80 ser
it shows 11 instance of ser with above info. If I sum up
617 * 11 = 6787 MB of memory but in my machine I've only 2 GB Physical RAM and it never uses Swap ?
if 54 * 11 = 594 ? but free -m and top shows more memory usage ?
can please explain me in brief . I'll be really thankfull. B'coz of this I'm facing may problem.
thanks
