Hi Prabhu,
Can you check the sha1 usage count in the lsmod?
I am thinking you have not freed the sha tfm and eventually run out of it.
I hit a similar issue when making use of linux sha1.
Thanks

Hi,
The SSL enabled client application seg faults when too many threads are
created. Each thread is a SSL client attempting a connection with Server.
The application sets the static call back functions.:
static void locking_function(int mode, int n, const char * file, int line)
static unsigned long id_function(void)
The application creates about 800 threads in a Linux 2.6 Kernel.

When less number of threads are created I don't see the issue.
How do we use CRYPTO_set_idptr_callback()? OpenSSL document reads - " There
is still the issue of platforms where pthread_self() returns something other
than an integer. It is for cases like this that
CRYPTO_set_idptr_callback() comes
in handy"
