I have an Ultra 10, 1gb mem, running Solaris 9. It is running apache2,
tomcat, postfix, and mysql.
It is not hit very hard and the total number of processes is not that
great. I looked in /proc and saw a lot of these entries:
dr-x--x--x 5 apache httpd 736 Sep 27 09:59 336
dr-x--x--x 5 apache httpd 736 Sep 27 09:59 337
dr-x--x--x 5 apache httpd 736 Sep 27 09:59 338
dr-x--x--x 5 apache httpd 736 Sep 27 09:59 339
dr-x--x--x 5 apache httpd 736 Sep 27 09:59 340
dr-x--x--x 5 apache httpd 736 Sep 27 09:59 341
These directories contain these files:
ganja:/proc/340 #ls -la
total 28628
dr-x--x--x 5 apache httpd 736 Sep 27 09:59 .
dr-xr-xr-x 78 root root 254400 Sep 27 14:39 ..

This box is in a colo right now and it is getting slammed by the current
windows viruses, so I get tons of these half-connects:
host.mydomain.com.http 130.94.13.99.1675 0 0 49312 0 SYN_RCVD
host.mydomain.com.http 130.94.114.9.1408 0 0 49312 0 SYN_RCVD
host.mydomain.com.http 130.94.166.161.1472 0 0 49312 0 SYN_RCVD
host.mydomain.com.http 130.94.12.72.1206 0 0 49312 0 SYN_RCVD
Is this something I need to worry about?
