During runtime mbedTLS allocates hughe amounts of memory. Depending on your
configuration, this is routed to the lwIP heap (see altcp_tls_mbedtls_mem.c).
If so, this value is *much* too low!

The other values might be too low, too. Try to increase everything to the max
(that your system allows) and see how much you actually need by monitoring
