Hi Alexey,

STDERR redirection to /dev/null must be on kill, not on wait:
	   kill $_tst_setup_timer_pid 2>/dev/null
	   wait $_tst_setup_timer_pid

Otherwise warning is issued when timeout occurs:
udp_ipsec 1 TINFO: run client 'netstress -l -T udp -H 10.0.0.1 -n 100 -N 100 -a 2 -r 500 -d tst_netload.res -g 49072'
udp_ipsec 1 TBROK: test interrupted
/opt/ltp/testcases/bin/udp_ipsec.sh: 46: kill: No such process

Kind regards,
Petr
