Re: [lwip-users] mbedtls

guess we are struggling with the same issue. I am using a TIVA TM4C129 Cortex M4 processor with 256K RAM. I can see that you connection also sometimes drops with an alert 2/46. I have activated the mbedTLS debugging and can see that this always happens after unsuccessfully trying to allocate a buffer of 16kByte. I have now reduced the number of connections down to 4 - although my webpages contain a lot of _javascript_ so that the browser tries to open more than 10 connections. But this is no issue. TCP will just not send an ACK on the received SYN, so the browser tries again later. For me this solved at least this issue. There are still others. As Mario said on your other thread: it seems it is a long way to go to optimize all.

The processor is the ATSAME70 with 384K SRAM, out of which the stack/heap is 250k so less than 130k is being used by static allocation. The web server works without https, and I have it setup for 10 connections.

The problem appears to be worse with DEBUG messaging off. However I do not have quantifiable data to prove this.

I am still learning about encryption but it appears that some connections are failing handshake.

What processor do you have, do you have enough RAM?
How do you turn off DEBUG problem occurs?
When the browser downloads each file, a new connection is made, which
consumes RAM. Process httpd for a permanent connection which is only
one handshake.
