Hi Denis,
It can mean different things. It’s best to inquire with your smsc themselves to ask them what this message means.

Hi guys, I noticed strange behavior of bearerbox (SMSC side of it) that most likely have been occurring for some long time but I just noticed it. In smsc log i see following warning message: "Maximum retries for message exceeded, discarding it!" and it comes right after submit_sm_resp that has an error from SMSC within it, for example: 2019-09-23 08:29:03 [11913] [86] DEBUG: SMPP PDU 0x7f209a72a760 dump: 2019-09-23 08:29:03 [11913] [86] DEBUG: type_name: submit_sm_resp 2019-09-23 08:29:03 [11913] [86] DEBUG: command_id: 2147483652 = 0x80000004 2019-09-23 08:29:03 [11913] [86] DEBUG: command_status: 8 = 0x00000008 2019-09-23 08:29:03 [11913] [86] DEBUG: sequence_number: 1840687 = 0x001c162f 2019-09-23 08:29:03 [11913] [86] DEBUG: message_id: 2019-09-23 08:29:03 [11913] [86] DEBUG: Octet string at 0x7f209a78aba0: 2019-09-23 08:29:03 [11913] [86] DEBUG: len: 2 2019-09-23 08:29:03 [11913] [86] DEBUG: size: 3 2019-09-23 08:29:03 [11913] [86] DEBUG: immutable: 0 2019-09-23 08:29:03 [11913] [86] DEBUG: data: 04 23 .# 2019-09-23 08:29:03 [11913] [86] DEBUG: Octet string dump ends. 2019-09-23 08:29:03 [11913] [86] DEBUG: SMPP PDU dump ends. 2019-09-23 08:29:03 [11913] [86] ERROR: SMPP[]: SMSC returned error code 0x00000008 (System Error) in response to submit_sm PDU. 2019-09-23 08:29:03 [11913] [86] WARNING: Maximum retries for message exceeded, discarding it!

I searched a lot about this warning message over the internet but couldn't find anything. Is there anyway to overcome this issue maybe?
