The issue might be linked to random initialisation, necessary for crypting operation of OpenSSL.
This  issue could be resolved by a UCONF parameter starting from V2.6.3

"CFTUTIL uconfset id=cft.seed.enable_internal, value=Yes"
This means that CFT will use internal random seed.

If the import works using internal random seed, and if the customer prefers to use system random service (more secure than product''s internal one), he should check that the "/dev/urandom" is well installed and he has rights to access it .
