Hello, Hope someone can shine a light for me on this, I have several boxes running STABLE 4/5/6 one of them is amd64/stable6 on dual opterons. I notice that on this amd system the httpd 2.2 and perl 5.8.8 binairies alocateds a lot of memory: 76562 www 1 20 0 156M 38528K lockf 0 0:00 0.00% httpd 76561 www 1 20 0 156M 38528K lockf 0 0:00 0.00% httpd 76830 www 1 20 0 155M 37740K lockf 0 0:00 0.00% httpd 76560 www 1 20 0 155M 37736K lockf 0 0:00 0.00% httpd 76563 www 1 4 0 155M 37736K kqread 0 0:00 0.00% httpd 61338 root 1 8 0 155M 37668K nanslp 0 0:02 0.00% httpd 73328 root 1 8 0 142M 102M nanslp 0 0:03 0.00% perl5.8.8 73611 root 1 8 0 142M 101M nanslp 0 0:03 0.00% perl5.8.8 75475 root 1 8 0 142M 99M nanslp 0 0:02 0.00% perl5.8.8 76966 root 1 8 0 142M 99M nanslp 0 0:02 0.00% perl5.8.8 75736 root 1 8 0 142M 101M nanslp 0 0:02 0.00% perl5.8.8 The binairy self has normal size: ~$ ls -lah /usr/local/sbin/httpd -rwxr-xr-x 1 root wheel 510K Apr 6 22:46 /usr/local/sbin/httpd ~$ ls -lah /usr/local/bin/perl5.8.8 -rwxr-xr-x 2 root wheel 12K Mar 4 09:48 /usr/local/bin/perl5.8.8 on the other systems (all i386 archs) the allocation for these binairies is a lot nomalizer, think about 52440K / 41492K : 26322 root 2 0 52440K 50040K poll 0:19 0.00% 0.00% perl5.8 26296 root 2 0 52340K 49964K poll 0:20 0.00% 0.00% perl5.8 26411 root 2 0 52328K 50024K poll 0:25 0.00% 0.00% perl5.8 69338 www 18 0 41492K 35560K lockf 2:00 0.00% 0.00% httpd 69387 www 18 0 29856K 23992K lockf 1:48 0.00% 0.00% httpd 69376 www 18 0 29816K 23940K lockf 1:49 0.00% 0.00% httpd Stripping the configs so that there is almost nothing in there , the allocated mem size still remains 150Mbs.. The only big diff in this case is the AMD64 arch. The packages are default builds from port. Anyone any ideas ? Thanks in advanced. patrick --
