I am using LWIP stack MQTT with TCP/IP. When I use single topic with multi segmented data then it works as expectation but If I subscribe/publish multiple topics with 1000bytes payload size or 2000bytes payload size it gets failed.

A lot of info is missing. Is the subscriber failing or the publisher? And why is the message fragmented if only 1000K bytes?
I had problems with fragmented messages, that is, messages larger than the TCP segment size. I modified the code a bit so that it works with large incoming messages. I'm testing my modifications with 6 subscriptions and with single messages upto 1 Mbyte.
