Hi
my server crashes every 90 minutes. There is no helpfull message in
any logfile, the only thing i can see is that smbd consumes 100% CPU.
The server hangs completely, no access to console, no networking. This
might have something to do with user logout. This server stands in a
school and about 150 pupils log out after each lesson. I assume it has
nothing to with printing, as printing is done directly over cups. I
use loglevel 2.
My smb.conf (excluding many shares):
[global]

I compiled Samba3.3.0 on OpenSUSE 11.1 with this flags:
Using FLAGS = -O -D_SAMBA_BUILD_=3
-I/usr/local/src/samba-3.3.0/source/popt
-I/usr/local/src/samba-3.3.0/source/iniparser/src -Iinclude
-I./include -I. -I. -I./lib/replace -I./lib/talloc

-I./libaddns -I./librpc -I./popt -DLDAP_DEPRECATED -I/include
-I/usr/local/src/samba-3.3.0/source/lib -D_SAMBA_BUILD_=3
PICFLAG = -fPIC
LIBS = -lcrypt -lresolv -lnsl -ldl
LDFLAGS = -pie -Wl,-z,relro -L/usr/lib64 -L./bin
DYNEXP = -Wl,--export-dynamic
LDSHFLAGS = -shared -Wl,-Bsymbolic -Wl,-z,relro -L/usr/lib64 -L./bin
SHLIBEXT = so
SONAMEFLAG = -Wl,-soname=
==========================================================================
BTW: I tried to set CFLAGS to -O0 with export CFLAGS="-O0" but "-O"
isn't the same as "-O0"?
What can I do to reproduce that error? Simply logging out or shutting
down _one_ PC does not suffice.
What can I do to track down my error?
This error occured after the update to OpenSUSE 11.1. The official
SuSE version had the same weakness.
The owner of the hanging smbd is root.
I changed from nss-ldapd to nss-ldap but that didn't help me with this
problem.
Any help is appreciated, thanks a lot
