Hi,

Method 1 was intended for qube´s only, i´ll take a look at it sometime to add a proper howto for the raq series.
Anyway, if you run a simple /urs/sbin/perl580 --version  does that also result in the message ? Or does that give proper output ?

There seem to be more reports of this problem. While the message indicated problems with a wrapper, shell, or cron-like script initiator, sometimes even the version request yields incorrect results, which might indicate problems and compiletime. Is the machine you used to compile the program a "real and original"  raq4, or an other cobalt with a newer os, (possible speed upgrade etc etc).
