5406zl hangs at 100% CPU wikh K14_47 but not with K13_47
I 'v got a problem with a 5406zl, firmware K_14_47, Rom version 12.20 with 6x 4-port 10Gb module (non mini Gbics).
When all 10gb Gbic are out the cpu stays low. When I put just one 10gb interface in one of the ports the cpu rockets to 100% cpu immediately.
The 5406 is configured with OSPF (ABR), VRRP, MSTP (no instances), IGMP, Multicast etc.
When I bring down the 5406 down to the previous version, K_13_47 all functions well.
Has anyone encountered this problem or a clue ?
Thanx Jaap

Re: 5406zl hangs at 100% CPU wikh K14_47 but not with K13_47
I would have done a 'show tech all' if the switch had not been so damned slow. Because of that and the existing closing service-window I had to return to the stable and working firmware version.
The strange thing is that the client has many other 5406s with the same modules and transceivers (HP ProCurve 10-GbE X2-SC SR Optic, J8436A) and they work just fine with firmware version K14_47 !?!?!?!
No clue so far. :)

The problem has been found.
As far as I heard it has to do with muticasting.
The problem has been reproduced by HP and one of its big partners in Holland.
A workaround has been configured.
HP has to solve this further in a new firmware version.
