Package: xdm
Version: 1:1.0.5-2
Severity: important

After a few days of normal work xdm hangs and doesn't respond to the remote
xdmcp queries anymore. It wastes CPU and does nothing.
I strace it, look below.

cheusov@syn-proc:~$ sudo strace -p 4319 2>&1 | head
Process 4319 attached - interrupt to quit
read(5, "", 4096)                       = 0
read(5, "", 4096)                       = 0
read(5, "", 4096)                       = 0
read(5, "", 4096)                       = 0
read(5, "", 4096)                       = 0
read(5, "", 4096)                       = 0
read(5, "", 4096)                       = 0
read(5, "", 4096)                       = 0
read(5, "", 4096)                       = 0
cheusov@syn-proc:~$

I used 'head' here because the list of read calls is unfinite.

Ok, let's mark this bug as fixed in 1.1.4-3 then.
