Hello

2/3 times a week a user is disconnected from the server, when this happens
the afpd process takes all the cpu power 100% forever.
There are no log messages that indicate that there was anything wrong.
The output of the gdb connected to that process is listed below. I added
some variables views. (these are all the commands i know at this moment with
gdb).
Is this interesting information, or what commands are interesting for
narrowing the place where it goes wrong or finding this bug.
The ibuflen is big, bud isn't used in that function, is this correct?
The while loop where the process hangs only breaks if the dir is found or if
the list is at its end. I'm don't know where the write error comes from, bud
is it an option to also break when a client is disconnected or an other
break so it doesn't keeps looping.

My config:
Netatalk 1.5.5
compile
options: --with-shadow --enable-timelord --with-did=cnid --enable-redhat --w
ith-cdb --with-db3=/usr/.......
I use db3.3.11
My system is Mac G4 with yellowdoglinux 2.3

Grtz,Remco and Merry Christmas
