owserver is multithreaded -- might separate threads appear as separate
processes in uclinux?

Hi Rob
Your message prompted me to check the processes on my slug.
PS looks a bit scarier than yours.
Why aren't old processes dying I wonder
Maybe more importantly why are new ones starting?
I 'm polling it every min to get data but I don't see why that would start
processes. Not using owread, just "cat filesystem > myfile"

*Subject:* [Owfs-developers] why are there 3 x owservers running on my
SLUG (NSLU2)
I have noticed using "top" that owserver takes 16% of my little slugs
memory when idle and 29% when my owread script kicks in.. This has led me
to wonder why I have three owservers running on my slug.
The only owfs services script remaining is the S70owserver script. The
other startup scripts (S80owfs, S80owftpd, S80owhttpd) I have moved out of
/opt/etc/init.d so they do not startup. I only have one data gathering
script which continuously runs and polls 1wire data every 90 seconds. This
script uses owwrite owread commands.
I have used the standard ipkg install process.. Anybody know why I have
three owservers running ?
