Top Citrix NetScaler Defects

Defect ID: NSHELP-41484
NetScaler might generate the lsof_<hostname> file each time you create a support bundle. However, the system fails to remove these files immediately after the generation process is complete.
Defect ID: NSHELP-42609
The NetScaler packet engine might crash due to a defect in backend TLS 1.3 connection state handling during teardown. On NetScaler SDX platforms with multiple instances, a crash in one instance can also affect other instances sharing the same crypto hardware.
Defect ID: NSHELP-41518
Client requests might fail if HTTP/2 header values contain space characters. These spaces can trigger header frame processing errors, particularly when the client sends improperly formatted header values.
Defect ID: NSBASE-19568
When the server-side TCP window reaches a 2 GB limit, the gRPC hold logic incorrectly opens the TCP window twice for held bytes, resulting in a zero window advertisement. This issue also includes incorrect accounting of chunk header and trailer bytes before they are passed to the application handler, affecting TCP window management and data transmission.
Defect ID: NSHELP-42103
Pitboss logs might sometimes flood ns.log when the SSLVPN or IC feature is enabled and cache memory is set to 492 MB, specifically when the number of NetScaler packet engines is 4 or 5.
