Quite strange, you can try a strace and check for communication with 
137.164.85.52:

# strace -e trace=network -ff 
/usr/lib/perfsonar/bin/perfsonar_meshconfig_agent 
--config=/etc/perfsonar/meshconfig-agent.conf 
--pidfile=/var/run/perfsonar-meshconfig-agent.pid 
--logger=/etc/perfsonar/meshconfig-agent-logger.conf --user=perfsonar 
--group=perfsonar
...
socket(PF_INET, SOCK_STREAM, IPPROTO_TCP) = 6
bind(6, {sa_family=AF_INET, sin_port=htons(0), 
sin_addr=inet_addr("0.0.0.0")}, 16) = 0
connect(6, {sa_family=AF_INET, sin_port=htons(443), 
sin_addr=inet_addr("137.164.85.52")}, 16) = 0
getpeername(6, {sa_family=AF_INET, sin_port=htons(443), 
sin_addr=inet_addr("137.164.85.52")}, [16]) = 0
