- Mon Apr 20, 2015 12:37 am #15089 Same here, and with each new SDK version the available heap size seems to be less and less, so this is an issue.
Hitting F5 20 times crashes the server now, looking forward to tips on solving this

I've added the missing free and I now the memory on the heap happily bounces back to what it should be. I've committed the change to git if you want to test it.

I assume there is more to that, and I am afraid it could be SDK issue rather than esphttpd issue..

- Tue Apr 21, 2015 4:39 am #15179 .. to answer myself: just tried it with SDK 1.0 and it seems stable now. Although SDK 1.0 uses 2K more heap (at least), it is handling better the TCP connections and the leak seems to be gone now, or at least for the 10 minutes of testing that I have been doing
