The slave device of my D64S ISDN leased line went down with this log

At 13:18 I did realize this and restarted the ISDN link (HiSax unloaded)
and everything seemed fine again.
I run the MRTG which connects to my providers Cisco every 5 minutes. In
the evening, I found some hanging processes and stopped the cron
process.

The interesting thing is, that this program should run every 5 minutes,
but not all of them hanged. All of them look like this
smuf:/var/data # ps lnwax | grep rate
100000 0 12330 12294 0 0 1116 240 1121b5 D ffff 0:00
/usr/bin//rateup /usr/local/httpd/htdocs/huwig.de/www/mrtg/
xxx.xxx.de.14 924181
i.e. hanging at 0x1121b5; from System.map:
00112118 T __up
00112130 T __do_down
001121f0 T __down
'lsof' gives:

'netstat -a' shows no connections to the cisco, but 8 connections to
Squid are hanging in "CLOSE" state for several weeks.
Any clues? Please reply via eMail, as I am not subscribed.
