What are you plugging into this new VLAN?

One thing that comes to mind is the 2524 has a single mac-address forwarding table. If it sees the same mac-address on different VLANs you will packet loss issues.

I am plugging RJ45 cables ,conneting my server to 2524 .
I see in the specs of 2524 that it supports 30 VLAN's .Then why do i get this problem .
