Hello,
I have 4 web servers with lighttpd to serve one web site with DNS load
sharing. On the 2 SMP-enable web servers, there will be many php-cgi frozen
in 'sbwait' state every day. It means the php-cgi stay in 'sbwait' state,
and never be back to 'accept' or other state. If I restart them, there will

Odd 'hang' trying to ls a directory ...
...run 'df -t ufs', as that too just hangs ...
According to ps axl, I have the following in WCHAN states:
neptune# ps axl | awk '{print $9}' | sort | uniq -c
6 -
1 WCHAN
207 accept
103 inode
2 kqread
412 lockf
68 nanslp
8 pause
1 piperd
13 poll
3 psleep
58 sbwait
1 sched
626 select
1 syncer
3 ttyin
1 vlruwt
8 wait

system? A few minutes later, there are a few variations:
neptune# ps axl | awk '{print $9}' | sort | uniq -c
6 -
1 WCHAN...
