asteriskLogger STOP RUNNING

[birdsystem]

Good Morning!

I'm having problems with constant stops of the process asteriskLogger

always run the command:
/ html / Asterisk # nohup php asteriskLogger.php> asteriskLogger.log &

But sometimes the log stopped and the process does not feed the table as it should
I always have to stop the process and start it again to return to normal

the latest information that appears in the log are:

--- Mysql_checked_query ()
+++ Mysql_checked_query # ()
! SQL: UPDATE asterisk_log SET callstate = 'Hangup' timestampHangup = NOW (), hangup_cause = 20, hangup_cause_txt = 'Unknown' WHERE channel = 'Local / ag1023 @ business'
Rows affected: 0

+++ FindSugarObjectByPhoneNumber # ()

Can someone help me?
