-----BEGIN PGP SIGNED MESSAGE-----
I don't know how to really explain this odd problem. All I can say is that when I execute/use most programs/daemons (perl, sshd, etc) it takes numerous seconds before the process starts processing. Once the program starts responding, the program performs as I would expect. This started happening after the machine hung on the way down (init 6) and I had to reset it.
Examples: - - It takes 10 seconds to connect to the machine remotely via ssh. Used to be closer to 2 or 3. - - A simple Perl script "stalls" for about 3 seconds before doing anything. - - Connecting to Apache takes about 3-5 seconds, but then it serves a simple static page (no graphics) virtually instantaneously.
A few other programs such as 'top' and 'pine' don't seem to have a noticeable problem. I'm in a real jam here, this system is supposed to go into production as a web server, and the performance sucks so bad for even the simplest page (it's even worse for CGI's) that I'm having to hold off until this is fixed.
One other (perhaps unrelated issue) is that since the reboot, that running via /etc/profile: ulimit -c 1000000 causes the following error:
bash: ulimit: cannot modify limit: Operation not permitted
Any help/advice is extremely welcome.
