[Asterisk-Users] Mystery PRI NOTICEs & WARNINGs

[Bruce Komito]

Since connecting a PRI to a Digium T100P, I have been seeing the
following messages in syslog every few minutes:

Jun  4 06:51:54 pbx asterisk[13435]: WARNING[1209214400]: chan_zap.c:6176 in zt_pri_error: PRI: Read on 56 failed: Unknown error 500
Jun  4 06:51:54 pbx asterisk[13435]: NOTICE[1209214400]: chan_zap.c:6913 in pri_dchannel: PRI got event: 8 on span 1

Sometimes, these messages come out as often as six minutes apart, and
sometimes as infrequently as every hour.  I haven't noticed any
PRI-related problems coincidental with the messages. I am experiencing a
large number of dropped calls, but the dropped calls occur both on PRI and
non-PRI calls.

Has anyone observed these messages, and if so, do you know what they mean
and are they something to be concerned about?

Thanks in advance.
