Hi Experts,
I am working on a logging tool which receives messages from a server through socket. The socket uses SSL. Number of times, "under heavy traffic" my server crashes. The traceback from the thread that crashed shows the following:
11e0198 Send2Client +2f0: MiSslWrite ()
136b518 MiSslWrite +74 : SSL_write ()
135db00 SSL_write +50 : ssl3_write ()
1355adc ssl3_write +100: ssl3_write_bytes ()
1357758 ssl3_write_bytes+d8 : 13577cc ()
1357a5c ssl3_write_bytes+3dc: tls1_enc ()
Someone pointed out that if the stack size of the thread is small and needs to be increased. But, how they are connected. When the TCP send buffer becomes full( in fact as a result of the tool not reading the messages fast enough), would that increase the stack?
Thanks,

It depends on how your thread allocates the storage for the buffer. If you are using something like
BYTE* pBuf = new BYTE[SOME_SIZE];
the memory will be allocated from the heap. A construct like
BYTE aBuf[SOME_SIZE];
would place it on the stack. I somehow doubt that the thread's stack size is the reason for that, since the default stack size for a thread is 1MB, which usually is enough.
