Hi,

On a shared server with a large number of accounts

################
sites-enabled]# grep "server {" *|wc -l

The memory usage of nginx is very high
--------------------------------------------------------------------------

Private + Shared = RAM used Program
1.6 GiB + 4.9 GiB = 6.5 GiB nginx (3)
-----------------------------------------------------------------------------

# cat /proc/2068600/maps
00400000-006d6000 r-xp 00000000 09:7d 105657122
/usr/sbin/nginx
008d5000-008d6000 r--p 002d5000 09:7d 105657122
/usr/sbin/nginx
008d6000-008fe000 rw-p 002d6000 09:7d 105657122

008fe000-00921000 rw-p 00000000 00:00 0
0218b000-a2217000 rw-p 00000000 00:00 0

a2217000-13fbc7000 rw-p 00000000 00:00 0
[heap]


------------------------------------------------------------------------------------
pmap 2068600

2068600: nginx: master process /usr/sbin/nginx -c /etc/nginx/nginx.conf
0000000000400000 2904K r-x-- nginx
00000000008d5000 4K r---- nginx
00000000008d6000 160K rw--- nginx

00000000a2217000 2582208K rw--- [ anon ]
---------------------------------------------------------------------------------------

It looks like the heap is 2.6GB in size.

Is there a way to reduce this?

The configuration is not the problem ( which is why I am not attaching it)
as systems will a smaller number of vhosts using the same config consume
less ram
