[Tony Tin]

Hi,

I've Digium TE220p and 4ess ISDN with openzap native pri stack. I found
there are a lot of errors as below in the freeswitch.log. It seems that it
doesn't affect the operation of system at the beginning, but finally
freeswitch stop answering call. Could anyone help me. Thanks.

1. What's the cause of this error message.
2. How to avoid.
