- Subject: read -t hangs sometimes with pipes
Hi,
Sometimes pipes, created with mknod, seems not to be work fully correct.
Most of the time I can do:
mknod /var/run/CONT p
read -t 2 signal < /var/run/CONT.
After 2 seconds I receive a timeout and the read returns.
But sometimes the read will wait forever. And also if I write something
to /var/run/CONT, the read did not read it.
Furthermore I can not "reset" anything. I have to reboot the workstation
thats pipes works again.
Is there any posibility to reset something that pipes will work again
without reboot?
Thanks
Matthias
