About every hour I see the yellow alarms on all or a number of channels of
my PRI which is connected to the dutch telephony network, Asterisk keeps
on working fine....
Here's an example where channel 1-24 went into alarm:

WARNING[90124]: File chan_zap.c, Line 4139 (handle_init_event): Detected
alarm on channel 1: Yellow Alarm
WARNING[90124]: File chan_zap.c, Line 4139 (handle_init_event): Detected
alarm on channel 2: Yellow Alarm
...
...
WARNING[90124]: File chan_zap.c, Line 4139 (handle_init_event): Detected
alarm on channel 23: Yellow Alarm
WARNING[90124]: File chan_zap.c, Line 4139 (handle_init_event): Detected
alarm on channel 24: No Alarm
....
....
And right after that they are cleared again:
NOTICE[90124]: File chan_zap.c, Line 4134 (handle_init_event): Alarm
cleared on
channel 1
NOTICE[90124]: File chan_zap.c, Line 4134 (handle_init_event): Alarm
cleared on
channel 2
....
....
ending with:
WARNING[81931]: File chan_zap.c, Line 5137 (zt_pri_error): PRI: Read on 69
failed: Unknown error 500

Zaptel.conf has:
# E1 card
span=1,1,0,ccs,hdb3,crc4
# T1 card
span=1,0,0,d4,ami
# E1
bchan=1-15
dchan=16
bchan=17-31
# T1
fxoks=32-55
#

Any ideas on how to get rid of these alarms?

Thanks!
