> vnc_password is an encrypted field. During any list VM query this field is decrypted and then returned. In a scaled up environment if many simultaneous list VM queries are run then this may result in blocked threads as shown below. A single instance of StandardPBEByteEncryptor is used for encryption/decryption. Due to this all decrypt calls during list VM queries get blocked as the decrypt method is thread safe (see http://www.jasypt.org/api/jasypt/1.8/org/jasypt/encryption/pbe/StandardPBEStringEncryptor.html)
