Re: [lwip-users] Randomly delayed frame (STM32070 package including LwIP

Two suspects:

1. DMA/Buffer issue from LwIP into the Ethernet Peripheral.
-> Because the behavior depends on packet/traffic loading
-> Do other types of traffic produce the same effect?

2. Memory corruption (perhaps unlikely due to the fact that "most" packets
are making it)
-> Is loading your webpage accidentally overwriting some control structure
in LwIP causing the stack to hiccup?
