asterisk users - May 2011 - chan_zap

Hi All;

Suddenly the zaptel channel look like stop working and it is giving me this
error when I do zap restart:

[May 24 19:30:21] ERROR[2772]: chan_zap.c:7219 mkintf: Unable to open channel 1:
Device or resource busy
here = 0, tmp->channel = 1, channel = 1
[May 24 19:30:21] ERROR[2772]: chan_zap.c:10582 build_channels: Unable to
register channel '1,2'


To what it could be related?

Is it related to any thing in the configuration or it is related to the software
it self (for example some file is crashed)? What is the fastest way to recover
it?

Regards
Bilal

It is already open by something else? Another program? A different
instance of Asterisk?

Dear;

I did restart for asterisk and actually i restarted the machine using init 6 but
the problem still the same.

I run zttool and it gives OK and not REC, also when I pressed F1 for more
details I saw that
Current Allarms: No Allarms
Sync source: Internally clocked

IRQ Misses:               0                             
Bipolar Viol:             0                             
Tx/Rx Levels:         0/  0                             
Total/Conf/Act:       4/  4/  0                         

So what could be my problem?
Appreciate if someone can help me? How can I know if the hardware is damaged or
not?

Regards
Bilal
