  • 10.5-65.11 Updated: February 10, 2017 | Release notes version: 1.0

    This release notes document describes the enhancements and changes and specifies the issues that exist, for the NetScaler

    release 10.5 Build 65.11. See Release History.

  • Fixed Issues The issues that are addressed in Build 65.11.

    AAA-TM

    The NetScaler appliance does not set the cookie domain that is configured in authentication profile specified at LB/CS

    vservers.

    Due to this, cookie is set for domain on authentication vserver fqdn but for host at CS/LB vserver. This causes issues

    when cookie is being expired programmatically, such as responder policies.

    [# 594634]

    • In a high availability setup, a session does not time out even if a force timeout is configured on a traffic action that is

    bound to a load balancing or content switching virtual server and a force fail over is performed.

    [# 623053]

    • In a multi-core NetScaler environment, user sessions sometimes do not get terminated if the decision to terminate is

    based on a force timeout value that is configured on a TM traffic action.

    [# 610604, 618760]

    AppFlow

    • A NetScaler load balanced server responds with a 411 error code for a corrupted HTTP request.

    [# 629223]

    Application Firewall

    • The Onhover pattern has been added to the default list of cross-site scripting (XSS) denied patterns that the

    Application Firewall looks for when scanning traffic.

    [# 665595]

    • Executing force sync operation using the nssync -s command from the shell triggers NetScaler appliance reboot and

    crash. The nsnetsvc crash occurs when the import filename length exceeds MAX_FILE_PATH_LEN.

    [# 657920]

    Configuration Utility

  • • If you create a cipher group and do not add any ciphers to it, an error message appears when you try to open the

    cipher group in the configuration utility.

    [# 604646]

    DNS

    • If the DNS server from which the cached DNS records are being served goes DOWN, the proactive DNS update queries

    are redirected to the back-end server.

    [# 660562]

    • When the NetScaler appliance receives a DNS TCP packet that has dnspayloadlen as zero, the NetScaler appliance

    might dump core memory.

    [# 666803]

    • A NetScaler appliance might fail while performing DNSSEC offloading if insufficient memory results in memory

    allocation failures.

    [# 594535]

    DataStream

    • The DataStream feature does not work if you use a MySQL database at the back end.

    [# 629504]

    GSLB

    • In a GSLB high availability setup, if a node stays in secondary state for more than 249 days, the service state might not

    be updated on this node after it becomes the primary node.

    [# 658093]

    • The MEP connection for site metrics goes DOWN if the dynamic RTT and GSLB server persistence features are unused

    for more than 249 days. In some cases, however, the MEP connection for site metrics remains UP, but the MEP

    connection for network metrics goes DOWN.

    [# 658890]

    Load Balancing

  • • If a GSLB service goes DOWN and then returns to the UP state, the configured hash-based load balancing methods

    might produce incorrect load balancing decisions, because the cache maintained for hash-based
