Hi,
for evaluating purposes I'm trying to send quite big amount of data (100 kB) via socket interface. Sending proceeds fine until approximately 60 kB is transmitted. After than SEGGER debug window shows following stack trace and transmission is interrupted.

I'm trying to send HTTP PUT message via socket interface. Size of each transmitted package is 512 bytes and there is one second sleep between each package. Message size of 50kB can be transmitted without errors. Any idea what might go wrong with bigger data sizes?
