RTCS Out of Memory after sending 500 EMails

[Stefan_75]

Hi,

i've made an EMail implementation like in the security email demo.

To make a test i'm sending every 3 seconds an email. After 500 mails the RTCS Task is out of Memory. At this moment creating a socket is possible, bind() also, but connect() returns error 0x1612 (RTCSERR_TCPIP_NO_BUFFS).

RTCSTASK_stacksize is set to 4000. 

Anyone any idea?

Thanks for any hint.

Hi,

I'm shutting down the socket before receiving all TCP messages at the end. In my case I'm sending a lot of EMails in a very short time. It seems to me, when I'm shutting down the socket, the rest of the incomming messages in the buffer for the expired socket won't be removed from the buffer, or it takes a longer time. But this didn't explain, why the task is out of memory. For my understanding, if the buffer is full, the RTCS should refuse any more messages.

Now I'm wating for the TCP [FIN] message and I don't have the problem any more. (Tested for > 3000 EMails). Shutting down don't generate a [RST] message any more.
