Tried your suggestion, but No change. Seems the issue is with the apm_gunzip_cmd in the /var/lib/aolserver/valhalla/packages/acs-tcl/tcl/apm-file-procs.tcl
file. I think it is an issue with the switches (-q -c) but tried adding the -S (suffix switch with .apm), but still error with this line:
"exec [apm_gunzip_cmd] -q -c $file_path | [apm_tar_cmd] tf - 2>/dev/null"
