Intermittently SSL connection fails with this message in server log SSL3_GET_RECORD:decryption failed or bad record mac

I am intermittently detecting ssl communication to fail with [1]. I've seen the issue only on Solaris 10 boxes (both intel and sparc). It happens intermittently for different test cases (one way ssl or two way ssl).

This happens only when using wildfly openssl with openssl (Seen with JBCS openssl 1.0.2h)

Any idea what could be causing the issue?
