I'm trying to use openssl-0.9.7a-23 (the RPM from Fedora 1) in a multithreaded environment.
Basically I have a server with about 5 worker threads and a client with a varying number of threads that connect to the server. When using around 20 threads at the client I can't see any problems. But when the client increases to around 150 threads the client segfaults. The server never segfaults. The gdb trace is: Program received signal SIGSEGV, Segmentation fault. [Switching to Thread -1431196752 (LWP 15771)] 0x00620b84 in _int_malloc () from /lib/tls/libc.so.6 (gdb) where #0 0x00620b84 in _int_malloc () from /lib/tls/libc.so.6 #1 0x0062170a in _int_realloc () from /lib/tls/libc.so.6 #2 0x0062012f in realloc () from /lib/tls/libc.so.6 #3 0x00b70307 in OpenSSLDie () from /lib/libcrypto.so.4 #4 0x00b70a06 in CRYPTO_realloc () from /lib/libcrypto.so.4 #5 0x00bb84f4 in lh_doall_arg () from /lib/libcrypto.so.4 #6 0x00bb8248 in lh_insert () from /lib/libcrypto.so.4 #7 0x00000001 in ??

() ( Within main I do the calls to: CRYPTO_set_id_callback((unsigned long (*)())pthreads_thread_id); CRYPTO_set_locking_callback((void (*)())pthreads_locking_callback); One thing I'm not sure from the documentation is whether or not the ctx can be shared across multiple threads. At this point I am using a pointer to the same ctx everywhere and call the SSL_new each time a connection needs encrypting. Any ideas as to where I need to be looking to figure this out?
