Memory leaks are observed for libgcrypt.so.11 in multi-thread mode

[tangtong]

Hi,
My program is a multi-thread server(pthread) working in Solaris enviorment, For thread-safe consideration, according to the guide, I have defined the following macro and call the specific function during iniatlization:
GCRY_THREAD_OPTION_PTHREAD_IMPL;
 gcry_control (GCRYCTL_SET_THREAD_CBS, &gcry_threads_pthread);

Scenario1:
Launch Tls session one after another to guarantee there is no concurrency existing between tls session, there is no memory leak reported by MDB;


Scenario2:
Launch TLS session concurrently, e.g., 50 TPS,  memory leaks are reported by MDB

I have disabled the session reusage and deinit tls sessions structure with gnutls_deinit().

Anybody can give me some tips on this issue?

Tony
