  • The following messages in the ASE startup could also occur.  All of which involve ks_falloc routines:
    • When the server starts up not all engines come online, the following are examples of 3 different types of errors may be seen:
      No memory for Network Buffers bucket pool growth (113725440 bytes)
      ks_falloc: Cannot allocate using ubfalloc(rnetmempool, 32).
      Initialization of RSA algorithm for network password encryption failed, algorithm is not available for password encryption.
      Encryption provider initialization failed on engine 22.
      Server layer intialization failed for engine 22
    • Initialization of RSA algorithm for network password encryption failed, algorithm is not available for password encryption.
      ks_falloc: Cannot allocate using ubfalloc(rnetmempool, 32).
      Initialization for the SHA algorithm failed, authentication and on-disk password encryption will not work.
      Encryption provider initialization failed on engine 2.
      Server layer intialization failed for engine 2
    • ks_falloc: Cannot allocate using ubfalloc(rnetmempool, 48).
      SSL or Crypto Error Message: 'sybcsi_profile_create'.
      SSL or Crypto Error Message: 'csi_cipher_setup'.
