PING to one host in one background process

Hi All,
I'm doing one script on Juniper router where you have one FreeBSD Shell:
Is pinging from time to time one ethernet port of othere router and in case of fail is blocking one port entering in CLI and doing some command:
If I run this script all is working perfectly, but if I run in Backgroung using "&" is blocked on ping (ping -c1 $RemoteIPAddress) . Could you help me to solve this problem?

Many thanks
giancarlo

NAME

       scrollkeeper-rebuilddb - rebuild the scrollkeeper document catalog database

SYNOPSIS

       scrollkeeper-rebuilddb [-p path ] [-v] [-q]

DESCRIPTION

       This rebuilds the ScrollKeeper database from the original OMF metadata files and documents.  Under normal situations, this tool is not nec-
       essary.	It is useful however if the database becomes corrupt, which could be caused by interruption of ScrollKeeper during  an	update	of
       the database.

       Errors and warnings are logged to /var/log/scrollkeeper.log.

OPTIONS

       -p path
	      Use path as the ScrollKeeper database directory.

       -v     Verbose.	Show warnings and error messages in addition to logging them to /var/log/scrollkeeper.log.

       -q     Run  in  quiet  mode, suppressing output of all but the most serious warning and error messages to STDOUT.  Note that most output to
	      the log file will be unchanged.
