check_procs with -a argument

[Frost, Mark {PBG}]

I must admit I'm a little confused about using the check_procs plugin.
The help shows that you can use the -a argument to match against args in
the command as follows:

 -a, --argument-array=STRING
   Only scan for processes with args that contain STRING.

I'm trying to trap a process that's running under ksh.  If I run

check_procs -C ksh

I get 

PROCS OK: 7 processes with command name 'ksh'

(as I expect).  The specific process I want to match shows in 'ps' as

401 S   foo   1079  1062  0 158 20 e00000019523e280  111
e00000013c2de000  Feb 20  ?         0:00 ksh
/opt/zib/fit/asn_nex/OFH1/scripts/runnex.sh /opt/java1.4/jre
/opt/zib/fit/asn_nex/OFH1/bin/

but if I run

check_procs -C ksh -a runnex.sh
check_procs -C ksh -a "runnex.sh"
check_procs -C ksh -a "OFH1"
check_procs -C ksh -a "/opt/zib/fit/asn_nex/OFH1/scripts/runnex.sh
/opt/java1.4/jre /opt/zib/fit/asn_nex/OFH1/bin/"

all I get in response is

PROCS OK: 0 processes with args 'runnex', command name 'ksh'

or variants of that.

What am I missing here?  Am I not listing all or part of arguments to
ksh?

Thanks

Mark
