Re: [Discuss-gnuradio] catching unrecognized exception

[Nemanja Savic]

Dear gnuradioers,

I would like to ask againi if somebody can help me understand this:
thread[thread-per-block[0]: <gr_block db_logger2 (62)>]: caught unrecognized exception

I have two blocks of db_logger type and it looks like only one catch this unrecognized exception and another keeps working fine.

best and thank you

Hi all guys,

I have a block which is responsible to receive certain messages from other blocks and to write the data from the message into database. Sometimes the following exception occures and the block stops writing into database:

thread[thread-per-block[0]: <gr_block db_logger2 (62)>]: caught unrecognized exception

The structure of the block is really simple:

    def handle_msg(self, msg):
        message = pmt.pmt_symbol_to_string(msg)
        msg_lines = message.split('\n')
        try:
            sensor_id = msg_lines[0]
            vendor = msg_lines[2]
            sensor_type = msg_lines[3]
            time = msg_lines[1]
#try:
            querry = "INSERT INTO `%s`.`%s` (`id` ,`sens_id` ,`vendor`, `sensor_type`, `det_id`) VALUES (NULL , '%s', '%s', '%s','%s');" % (self._db_name, self._det_table, sensor_id, vendor, sensor_type, self._id)
#            print querry
            cur = self._con.cursor()
            cur.execute(querry)
        except mdb.Error, e:
            print "Unexpected error while trying to insert into table"
            print msg_lines
            print 50*'-'
            print "Error %d: %s" % (e.args[0],e.args[1])
            sys.exit(1)

Is there any way to track this problem and find the cause?

Best regards,
