All working fine but some how my network is getting down. Is it a right way using cron. Is there any mistake in procedure i m using. Please help

The cron job in and of itself cannot break your network, however, those php scripts could depending on what is happening inside them. There does not appear to be an issue with how you are calling cron, however, you might want to make sure your scripts are stepping on each other. Additionally, running all those network testing scripts at once may essentially be causing a self-induced denial of service attack.
