I've been trying to track down a problem on my e-mail server where it
stops processing smtp and pop processes for 5 minutes at a time.
# wc -l /etc/passwd
14945 /etc/passwd
We rebuild this file once per hour to add or remove customers.
I finally caught it with a top session running at the time.
Inetd was accepting new connections and starting popper but people can't
authenticate.
Sendmail accepts new connections but they stall until pwd_mkdb goes away.
When I try to run a command from the command line, it doesn't execute
until pwd_mkdb gets done.
The CPU is 97% idle during this time.
Does all file access in the system stop while pwd_mkdb runs?
3.2-STABLE June 30ish. SMP
