Hi,
Unfortunately kannel's I/O logging is very inadequate. Socket id is not at
all useful. However, looking at the logs more carefully:
ERROR: Error writing 16 octets to fd 29:
ERROR: System error 32: Broken pipe
ERROR: Couldn't write Msg to box <127.0.0.1>, disconnecting
DEBUG: Thread 19 (gw/bb_boxc.c:boxc_sender) terminates.
ERROR: Error writing 16 octets to fd 29:

.

.
WARNING: smsbox_list empty!
Shows that smsbox died (or whatever else was connected as smsbox). This is a
serious warning, which means that SMS are not sent upstream and instead
accumulate in store until smsbox reconnects. smsbox router wakes up and
rechecks every 30". This probably is the cause of your delays.
BR,
Nikos

That's an interesting story.
Now 5000 msgs is different than just 10. But if it happens with 10 messages
at a time, things might be more reproducible.

Hi,
I've also had similar problem some time ago when I was sending some
bulk of 5.000 msgs. There was sometimes "Broken pipe" error and
several problems with some DLRs (PDU unpacking failed). I tried to
reproduce this problem but I was not able to get those errors anymore,
it was happening one time when there was a huge traffic.

Hi,
I kept playing around with the configuration files but still no
luck. Today I tried to send 20 sms to smppbox but my smppbox or kannel
kept stalling again.
My system receives some 6 sms from my client and than it stalls for
1 minute or so before it continues receiving the rest. Moreover, my client
does not
receive all the deliveries back. It gets some 12 out of 20. I
checked my log files and I noticed several error and warning messages. In
my smppbox.log I
get the following error and warning messages periodically.

Most of all the error about the "Broken pipe" alerts me, I don't
know what that means but it seems to be serious.
I don't know if that can be the reason.
My current configuration is as follows:

I would really appreciate any help and ideas. I don't know how to tackle
this problem ;)

Onlly 10 sms is nothing of course. I wouldn't even call it bulk sms.
Is there anyone else with the same problems? Because if so, it seems a
serious enough issue to look into.
