5500G stack unexpected reboot

Hi,



I have a stack of 8 5500G (6x 24 port RJ45, 2x 24 port SFP) which partly rebooted without a clear reason.



Only a strange hint in the log buffer, tons of this message:



DRIVER/5/WARN:- 1 -


 ##### IUC_Q_FULL


 



As far as I know from the uptime (display version), at least one unit did not reboot, chances are high the 2 SPF switches survived but the 6 other reboot but I did not check every single switch.



Any ideas what IUC_Q_FULL means?



Anybody else ever had an unexpected reboot?



 



Regards



Henning

Re: 5500G stack unexpected reboot

Have the same problem.

As result no resync XRN-Fabric (4 units) and some ports gigabit ethernet do not work properly.

for example

 

port 3/0/18 does not forward packets.

and I have more such ports  with link-aggregation. This ports are used for uplinks to Access layer switches.

interface GigabitEthernet3/0/18
stp edged-port enable
port link-type trunk
undo port trunk permit vlan 1
port trunk permit vlan 10 20 30 55 70 80 90 120 150 990
port trunk pvid vlan 990
broadcast-suppression pps 3000
undo jumboframe enable
lacp enable
port link-aggregation group 18
apply qos-profile default
#
return


display cur int g4/0/18
#
interface GigabitEthernet4/0/18
poe enable
stp edged-port enable
port link-type trunk
undo port trunk permit vlan 1
port trunk permit vlan 10 20 30 55 70 80 90 120 150 990
port trunk pvid vlan 990
broadcast-suppression pps 3000
