Hi all I use libcsoap 1.1.0 library, to call some HTTP/HTTPS web services. libcsoap in turn uses OpenSSL for authenticating the secure sessions (HTTPS).
Both HTTP and HTTPS web service are functioning well and I get the proper response in both cases. But I found many memory leaks when I try to call HTTPS web service (which involve OpenSSL library underneath). For better clarification, I have attached the trace of Valgrind on the Pastebin: http://pastebin.com/f1e222abd Here is the last lines.... 1. ==3290== LEAK SUMMARY: 2. ==3290== definitely lost: 268 bytes in 1 blocks. 3. ==3290== indirectly lost: 66,807 bytes in 23 blocks. *********************!!!! 4. ==3290== possibly lost: 0 bytes in 0 blocks. 5. ==3290== still reachable: 2,536 bytes in 118 blocks. 6. ==3290== suppressed: 0 bytes in 0 blocks. Above is the leak for per HTTPS request/response, On each succeeding request/response, leaks on line 2, 3 and 4 get incremented, only 4th leak -- still rechable -- remain as it is. I checked libcsoap library thoroughly, at the end it call the below two function for clean up any used memory, they are in sequence: *SSL_shutdown(sock->ssl) **SSL_free(sock->ssl) *Even though the leak is present and detected in valgrind.* *Is there any solution or work around for solving this leak. On searching the net i found to configure/compile openssl with -DPURIFY option. but it didn't worked. My system is Fedora 8, And OpenSSL Library version is 0.9.8b I also tried the latest openssl 1.0.0 Beta1, the same memory leaks comes there. Thanks msp
