Hi,

Once a day, * drops all calls (E100P board). Yesterday, I updated *
version to CVS but I got the problem again today. Monitoring log
files,
I found this messages just before:

Jan 14 09:14:15 WARNING[81926]: File chan_zap.c, Line 5758
(zt_pri_error): PRI: Read on 25 failed: Unknown error 500
Jan 14 09:14:15 WARNING[81926]: File chan_zap.c, Line 5758

(zt_pri_error): PRI: Read on 25 failed: Unknown error 500

Few minutes after this, everything becomes fine. Any clue?
    

just a guess here...

The simple answer is have you verified that loop timing is set up in 
zaptel.conf. If not in loop timing a slip could cause the drop.

Loop timing on span 2 as primary timing would be:
span=2,1,0,esf,b8zs

Does this happen at the same time every day? If so it does not sound 
like a timing issue. If at random times, it could be.
  
Hi Don,

You are right! Yesterday, my telco called me about slip. I changed timing and now it is ok.
