it seems that netatalk especially afpd doesn't like 2.1.108,
no problems, with 2.1.98 ....
What I did, i killed LPRNG 3.4.2 ( kill -TERM )
tried a lpq (doesn't work ok?)
After that afpd segfaulted.
Symptoms:
It seems to me that LPRNG leaves the printerports (networkports) in a state where the
machine
oopses after a short time.
-> You cannot restart LPRNG after a kill -TERM
(it claims that the printer ports are in use by another
printer spooler)
but after about a minute you can restart lpd. (Some timeout I
believe
--> the machine oopses with 50 % in the next hour
LPRNG 3.4.2 and netatalk 1.4b2 are from Redhat 5.1 contrib
This was a Redhat 5.1 (5.0 updated with 5.1) system.
Kernel 2.1.08 libc6 (2.0.7)
