No arp virus, Switch don't response ping and telent

Hello All  !

      we got a switch issue here for 4507R-E with two sup6l-e supervisor running sso redudant. and we found that sometimes client can't ping through the local vlan ip add on the switch , can't logon the cli by telnet too. In the direct connected network device such as access switch and ASA , can't ping or telnet the 4507R too. when we made a forceswitch to sso standby supervisor from console , the problem solve and everything get fine . after that, we switch angin back to the origin supervisor , fine too.

    before we made the supervisor forceswitch , we had check the system cpu usage is 15 - 20 % from console . also we had creat a new vlan 200,  attach the notebook to 4507's vlan 200 port , the notebook can't ping or telnet the vlan 200 ip interface too.

   we had try to change the ios version from 15.02 to 12.2(54) ,  use 3 sup6l-e supervisor both acitve / standby , place the supervisor in chassic solt4 / 5 too , all of these had no effect for this problem . 

   pls be kind give me some advice , thank you very much !

       we had setup a log server for this issue ,  logging level is 4, log server work fine (we cant find the log when we issue a ctrl+Z in cli ) , but got no log msg when that happen

     the switch's running-config just contain some vlan , vlan interface , static routing, vlan acl , no any thing else.
