It's a bug in smsbox that it didn't limit max allowed http connections.
The same bug is present in HTTP SMSC module. HTTP was fixed by me as I was
at Centrium/Wapme but unfortunately I didn't merged it and don't have
modifications anymore but it was really simple to fix. I will try to
provide patch this/next week.
as for the fact that MO messages are not retransmitted in smsbox: did you
enable retry in smsbox?
Thanks,
Alex

Hi,
Are you using as a OpenSMPP SMSC simulator the

or as another version?
Please email back the version you are using, so others can confirm your
results.

Sorry, it turns out the version of OpenSMPP we're using has been heavily
modified from the original - however, I have been able to reproduce the
problem using the latest version of SMPPSim, with the following
configuration options (modified only slightly from the stock
configuration):
SMPP_PORT=7011
SMPP_CONNECTION_HANDLERS=2
CONNECTION_HANDLER_CLASS=com.seleniumsoftware.SMPPSim.StandardConnectionHandler
PROTOCOL_HANDLER_CLASS=com.seleniumsoftware.SMPPSim.StandardProtocolHandler
LIFE_CYCLE_MANAGER=com.seleniumsoftware.SMPPSim.LifeCycleManager
MESSAGE_STATE_CHECK_FREQUENCY=5000
MAX_TIME_ENROUTE=10000
PERCENTAGE_THAT_TRANSITION=75
PERCENTAGE_DELIVERED=100
PERCENTAGE_UNDELIVERABLE=0
PERCENTAGE_ACCEPTED=0
PERCENTAGE_REJECTED=0
DISCARD_FROM_QUEUE_AFTER=60000
HTTP_PORT=8081
HTTP_THREADS=1
DOCROOT=www
AUTHORISED_FILES=/css/style.css,/index.htm,/inject_mo.htm,/favicon.ico,/images/logo.gif,/images/dots.gif,/user-guide.htm,/images/homepage.gif,/images/inject_mo.gif
INJECT_MO_PAGE=/inject_mo.htm
SYSTEM_ID=test
PASSWORD=test
DELIVERY_MESSAGES_PER_MINUTE=12000
DELIVER_MESSAGES_FILE=deliver_messages.csv
LOOPBACK=FALSE
OUTBOUND_QUEUE_MAX_SIZE=500000
INBOUND_QUEUE_MAX_SIZE=500000
DECODE_PDUS_IN_LOG=false
CAPTURE_SME_BINARY=false
CAPTURE_SME_BINARY_TO_FILE=sme_binary.capture
CAPTURE_SMPPSIM_BINARY=false
CAPTURE_SMPPSIM_BINARY_TO_FILE=smppsim_binary.capture
CAPTURE_SME_DECODED=false
CAPTURE_SME_DECODED_TO_FILE=sme_decoded.capture
CAPTURE_SMPPSIM_DECODED=false
CAPTURE_SMPPSIM_DECODED_TO_FILE=smppsim_decoded.capture
CALLBACK=false
CALLBACK_ID=SIM1
CALLBACK_TARGET_HOST=localhost
CALLBACK_PORT=3333
SMSCID=SMPPSim
However, SMPPSim isn't as fast as OpenSMPP, so I had to run 4 instances
on separate servers (with additional SMSC configurations in Kannel
accordingly) to reach an MO injection rate of ~600 MOs/sec (no MTs), in
order to trigger the problem.
At rates of ~450 MOs/sec, with no MTs, or ~350 MOs/sec + ~320 MTs/sec,
the problem did not surface.
Regardless of the SMSC simulator being used, MO injection rates of
around 600 MOs/sec (on the hardware I described before) triggers the
problem. Has anyone been able to reproduce this yet, or does anyone have
an idea why this might happen?
