Hi Paul
Here is a list of the network:
10.045092000800 10.865A92000800 10.C64692000800
10.0F4892000800 10.A61292000800 12.7EF922000000
10.3B2F92000800 10.A82692000800 29.780301000000
10.5C0F92000800 10.C00D92000800
The serial adapter is Link45. The temp sensors are read once every 4
seconds using the cashed path. The switches are rarely read/written to
and when they are the uncashed path is always used. All of the temp
sensors are DS18S20
I hear you on the owhttpd theorem - I will wipe out a script to hit the
web server and then will compare results. You are correct in that
owhttpd is still running but it has not seen the same load that I have
put on to owfs (just because I wrote the bash scripts way before owhttpd
existed).
A simple looped wget will do the trick for testing owhttpd. As to the
reliability of owfs directly talking to the serial device - so far its
rock solid. To give credit to you and the project I have been running an
older version of owfs for 4 years, same scripts - 4 second sensor reads
and it has not crashed even once!
Thanks
~B

Thanks for the bug report.
Can you tell me a little more about your setup? What kind of sensors are
you using, and how often are you reading the owfs filesystem?
I'm trying to figure out if it's a usage-dependent problem. owhttpd and
owfs share a lot of code, so perhaps if we hit owhttpd as heavily it
would crash, too.
Clearly I need to do some testing.

Hey Paul and owfs team,
Has anyone seen the following behavior:
All tests done on FC9 stock install straight from DVD and fresh
download of the latest owfs tar.gz
If I use owserver and owfs then after about 5-6 hours of
moderate volume of calls to /mnt/1wire using basic bash scripts (cat
commands to read temperature once 2-3 seconds using the regular path,
NOT the uncashed path) owfs crashes and exists.
The error logged is always the same:
Aug 28 05:13:26 localhost kernel: owfs[17343]: segfault at
5415265c ip 0016a96c sp 54152650 error 6 in
libow-2.7.so.4.0.0[12f000+53000]
Aug 29 05:07:20 localhost kernel: owfs[2388]: segfault at
52d8065c ip 0014c96c sp 52d80650 error 6 in
libow-2.7.so.4.0.0[111000+53000]
Once owfs no longer runs due to the crash, further tests were
done. At that time owserver still continues to run happy and owhttpd
also runs AND returns real data from the 1wire network so the owfs crash
is likely NOT due to a lower layer irregularity (say if owserver crashes
so will the upper layers). Owhttpd returns real values which was tested
by synthetically inducing some sensors to change readings (blow dryer)
and observing whether owhttpd will show the changes and it does!
However if I ONLY use owfs and have it talk directly to ttyS0
then it is 100% stable and it never crashes
I am looking for similar experiences so it will help me figure
out what's wrong.
Thanks
