Hi Mohammed, thanks for your reply. Unfortunately I won't be at my workplace again until next monday, so I won't be able to provide detailed logs since then. On the other hand, I can post the kannel.conf file currently in use on the test machine. Thanks again for your help. I'll post relevant log entries ASAP.
Cheers, Fabio ################################ # # BEARERBOX # ################################ group = core admin-port = 13000 admin-password = SECRET #status-password = SECRET admin-deny-ip = "*.*.*.*" admin-allow-ip = "127.0.0.*;192.168.1.*" smsbox-port = 13003 #wapbox-port = 13002 #wdp-interface-name = "*" box-deny-ip = "*.*.*.*" box-allow-ip = "127.0.0.1" log-file = "/var/log/kannel/bearerbox.log" access-log = "/var/log/kannel/access.log" store-type = spool store-location = "/var/spool/kannel" log-level = 1 #log-level = 0 sms-incoming-queue-limit = -1 sms-outgoing-queue-limit = -1 sms-resend-retry = 0 dlr-storage = internal ################################ # # SMSBOX # ################################ group = smsbox bearerbox-host = "localhost" sendsms-port = 13013 sendsms-chars = "0123456789 " log-file = "/var/log/kannel/smsbox.log" log-level = 1 #log-level = 0 access-log = "/var/log/kannel/access.log" ################################ # # ACCOUNT/SMSC MAPPINGS # ################################ # SMSC FAKEPLEX group = sendsms-user username = USERNAME1 password = SECRET1 name = user_smsc_fake user-deny-ip = "*.*.*.*" user-allow-ip = "127.0.0.*;192.168.1.*" forced-smsc = smscfake default-sender = mycompany max-messages = 3 concatenation = 1 omit-empty = 1 # # SMSC PRODUCTION group = sendsms-user username = USERNAME2 password = SECRET2 name = user_smsc_prod user-deny-ip = "*.*.*.*" user-allow-ip = "127.0.0.*;192.168.1.*" forced-smsc = smscprod default-sender = mycompany max-messages = 3 concatenation = 1 omit-empty = 1 # ################################ # # SMSC CONFIG # ################################ # SMSC FAKEPLEX group = smsc smsc = smpp smsc-id = smscfake allowed-smsc-id = smscfake host = <SMSC HOSTNAME (GATEWAY A)> port = 3205 receive-port = 3205 transceiver-mode = true smsc-username = USERNAME_SMSC smsc-password = SECRET_SMSC system-type = "mycompany3" service-type = 18170 max-pending-submits = 10 msg-id-type = 0x01 log-file = "/var/log/kannel/smsc.gatewayA.log" log-level = 1 group = smsc smsc = smpp smsc-id = smscfake allowed-smsc-id = smscfake host = <SMSC HOSTNAME (GATEWAY B)> port = 3205 receive-port = 3205 transceiver-mode = true smsc-username = USERNAME_SMSC smsc-password = SECRET_SMSC system-type = "mycompany3" service-type = 18170 max-pending-submits = 10 msg-id-type = 0x01 log-file = "/var/log/kannel/smsc.gatewayB.log" log-level = 1 # # SMSC PRODUCTION group = smsc smsc = smpp smsc-id = smscprod allowed-smsc-id = smscprod host = <SMSC HOSTNAME (GATEWAY A)> port = 3205 receive-port = 3205 transceiver-mode = true smsc-username = USERNAME_SMSC smsc-password = SECRET_SMSC system-type = "mycompany4" service-type = 16570 max-pending-submits = 10 msg-id-type = 0x01 log-file = "/var/log/kannel/smsc.gatewayA.log" log-level = 1 group = smsc smsc = smpp smsc-id = smscprod allowed-smsc-id = smscprod host = <SMSC HOSTNAME (GATEWAY B)> port = 3205 receive-port = 3205 transceiver-mode = true smsc-username = USERNAME_SMSC smsc-password = SECRET_SMSC system-type = "mycompany4" service-type = 16570 max-pending-submits = 10 msg-id-type = 0x01 log-file = "/var/log/kannel/smsc.gatewayB.log" log-level = 1 # Il giorno 07/dic/2011, alle ore 17:08, Mohammed Saleem ha scritto: Hi Fabio did you check bearerbox and smsbox for errors? Also share your full configurations.

We have developed a multithreaded application that sends HTTP GET requests to our internal Kannel proxy. Everything goes smooth up to 5 application threads. The problem is that when the number of threads goes beyond 5, the responsiveness of Kannel seems to fall down to the point that it doesn't even accept more requests. I couldn't figure out where the problem is, nor which parameters adjust to widen the number of possible concurrent requests. Are there any limitations on the HTTP side of the gateway? Shouldn't Kannel accept requests at max speed, queue them and then deliver to the SMSC according to the accept rate of the SMSC itself? I've read through the documentation multiple times but I couldn't find any solutions yet. Thanks a lot for your support! Cheers, Fabio
