Resolution
Workaround:
Modified the RAMDISK memory size in the z_maint.cfg andz_auto.cfg files. These files are found in %ZENWORKS_INSTALL_PATH\share\tftp.
e.g.
#====================== WARNING! ======================#
# DO NOT EDIT THIS FILE!
#
# Modifying this file is unsupported and can have
# unpredictable results on ZENworks Preboot Services
#======================================================#
ZENWORKSAPPEND 1
