The NaviServer does not produce the error with variable "bar", just tested the following snippet.
ns_eval {
ad_proc foo {bar} {
ns_log notice "hello, $bar"
}
}
if {"test_queue" ni [ns_job queues]} {
ns_job create test_queue
}
ns_job queue test_queue [list foo XXX]
Notice, that ns_job expects the script as a single argument.
all the best
