Error description

  • Problem Description:
IBM Sterling Secure Proxy Version 3.4.3.2

Intermittent timeout during SSL handshake

Local fix

  • STRRTC - MFT-9906
MM / MM
Circumvention: None

Problem summary

  • When using an HSM device to store SSL private keys, the SSL
handshake sometimes timed out because it took longer than 5
minutes to pull the key from the keystore. The PNode
disconnected due to timeout. Symptom:
  CSP900E Logged Exception : java.net.SocketException:
Underlying socket
  is not connected

Problem conclusion

  • Eliminated 2 redundant loads of the HSM keystore which were
causing a delay. Also added some extra debug to help track the
flow leading up to the handshake.

Temporary fix

  • SSP3432 iFix 4 Plus Build 287
