PPP sessions

[Vendra, Hari Prasad V V P Ch S (Hari Prasad)]

Hi,
	I am using Fedora 3  Kernel 2.6.9-1.667.
	After opening 155 PPP sessions. My system
	automatically hanging and rebooting.
	I don't know what could be the reason.
	I am using the following command
	
	/opt/ppp-2.4.3/pppd/pppd /dev/pts/159 -detach asyncmap 0 user
CLIENT1 noipdefault local noauth persist

	Could you please suggest me , how do i debug.

Regards
Hari
