SNMPtrap doesn't incoming in all lenght from proxy into server.

[GreenHorn]

Hello,

I have issue, where snmptrap doesn´t incoming in all lenght of message from proxy into server.

For example:
LAST DATA

25.06.2021 09:50:09

09:50:08 2021/06/25 PDU INFO: receivedfrom UDP: [SourceDestination]:Port->[MyProxy]:Port notificationtype TRAP transactionid 12 version 1 requestid 125

But in Proxy I see all message:

09:50:08 2021/06/25 ZBXTRAP IP_Source
PDU INFO:
receivedfrom UDP: [IP_Source]:Port->[MyProxy:Port
notificationtype TRAP
