[Serusers] How long does exec_msg wait for result??

Hi, In our ser.cfg we do a database query to determine if the dialed number is a valid subscriber, if the user dialed a wrong number then it is sent to an IVR prompt. This works well most of the time, but every now an then we see calls that were dialed properly yet they where transfered to the prompt. I would like to know how long exec_msg waits for the query result and if it is tunable. The database is on the same host as ser so the result should be very fast, yet I am unsure as to why it is failing to query the subscriber table many times a day. MySQL is set for 1000 connections and I am not seeing a problem here. Any other MySQL things to look at? Here is the code snippet: #Now check to see if Dialed Number is Valid for one of our Subs if (method == "INVITE"){ if (!exec_msg(' QUERY="select username from subscriber where username=\"$SIP_OUSER\""; RESULT=`mysql -uXXX -pXXX -e "$QUERY" ser`; if [ -z "$RESULT" ]; then exit 1; fi ;')) {# User Does Not Exist rewriteuser("9993"); log(1, "Wrong Number IVR Prompt\n"); route(6); break; }; }; Our estimates indicate this fails about 5% of the time.
