PVS 2407 BIOS based Target Devices crash on PVS reconnect.

Customers would typically encounter a requirement for a PVS reconnect when performing load balancing operations, for example when patching and rebooting PVS servers. PVS reconnect would also occur during normal operation if sufficient PVS retries are accumulated, or if there is a temporary network drop between PVS server and target device.
This behavior can be reproduced on BIOS target devices only, UEFI targets devices are not affected.  It is reproduced without other software involvement. 

When using BIOS based PVS targets in a PVS 2407 farm, customers are advised to use PVS 2402 Target Device software for BIOS target devices. 

Problem Cause

Citrix PVS engineering has identified an issue with BIOS based target device PVS reconnect in PVS 2407 (reference CVADHELP-26272).

Support for BIOS in Citrix Provisioning 
BIOS is deprecated from version 2203. In version 2311, targets configured to boot using BIOS continues to function. However, BIOS management dialogs have been removed from 2311 release 
You must migrate to using UEFI booting. All new features, such as IPv6 will be UEFI in the future.
