[Simh] OpenVMS 7.2 VAX telnet failure

Hi!
I'm running OpenVMS 7.2 VAX on a simh emulator, latest release
(V3.9-0 from simh.trailing-edge.com) and compiled with networking (libpcap,
no vde).
The emulator has got its own network card to which it's attached.
The host operating system is Linux, kernel 3.11.
My issue is that after an apparently random amount of time (usually a few
hours) the telnet server stops working.
I can't get any client to log in remotely - as soon as I connect to the
OpenVMS machine,
all I get is a blank character sequence, as follows (dumped by nmap):

Restarting the TCP/IP stack doesn't help.
Other services running on it (e.g. FTP server) are not affected.
Bringing the interface down and up again on the host machine doesn't help
either.
Here's my vax.ini:
;
; Load CPU microcode
load -r /usr/local/vax/data/ka655x.bin
;
; Attach non-volatile RAM to a file
attach nvr /usr/local/vax/data/nvram.bin
;
; This virtual machine has 64M memory
set cpu 64m
;
; idle value
set cpu idle=VMS
;
; Define disk drive types. RA92 is largest-supported VAX drive.
set rq0 ra92
set rq1 ra92
set rq2 ra92
set rq3 cdrom
;
; Attach defined drives to local files
attach rq0 /usr/local/vax/data/d0.dsk
attach rq1 /usr/local/vax/data/d1.dsk
attach rq2 /usr/local/vax/data/d2.dsk
;
; Attach the CD-ROM to its file (read-only)
attach -r rq3 /usr/local/vax/data/openvms72.iso
;
; Disable unused devices. It's also possible to disable individual devices,
; using a construction like "set rq2 disable" if desired.
;
set rl disable
set ts disable
;
; Attach Ethernet to a network interface
set xq mac=00-21-85-00-b7-a7
attach xq eth0
;
; Now start the emulator
boot cpu
Any thoughts?
Thanks for your help
