Power connect 6224 stack problem

Hi Guys,

I have similar problem as andycrisp had in subject ' Issues with 4 stacked 6248's '. I have 2 stacked switches 6224. Normally everything works fine. But during peak I can't log in to switch in any way but console cable. Pining from any part of network works awful, which means any one of the 15 pings reaches destination. When network stabilize everything works perfect. Both stuck switches run firmware 3.3.9.1 In logs I can see only repeating all the time error :

DEC 16 10:52:18 10.10.10.2-2 DNS_CLIEN[217288320]: dns_client_txrx.c(371)
612 %% DNS Client: osapiSocketRecvFrom returned error for addr 0xCF38D90. Indica
tes there is a stack error in receiving the DNS response packet from the server.

Which is strange cause configured DNS server is different.

I would be grateful for any suggestions.

Cheers!

Pawel

Regarding to counters only different thing I found is :

But as far as I know it is nothing which we should concern as long as bcmRX process is around 1%

SESW002#show interfaces counters ethernet 1/xg3

Transmitted Pause Frames: ..................... 0

Pause frames comes cause port on second switch has smaller bandwidth set

Regarding time, problem which I mentoined intensify during office hours.

And what does :

DEC 16 10:52:18 10.10.10.2-2 DNS_CLIEN[217288320]: dns_client_txrx.c(371)

612 %% DNS Client: osapiSocketRecvFrom returned error for addr 0xCF38D90. Indica

tes there is a stack error in receiving the DNS response packet from the server.

notification means?

Any suggestions?

Cheers!

Hi again,

Sorry for late answer. Yes, all output has been colleted while issue has been occuring. 1/g2 is connected to other 6224 switch which is connected to inter alia Vmware server farm, but to be honnest I do not think it can caused the problem(bcmRX process is around 2%).

Any suggestions?

Cheers

Hi Daniel,

I've just upgraded firmware:

image1 : default image

image2 :

Images currently available on Flash

--------------------------------------------------------------------

unit      image1      image2     current-active        next-active

--------------------------------------------------------------------

   1    3.3.12.1     3.3.9.1             image1             image1

   2    3.3.12.1     3.3.9.1             image1             image1

I did failover (just to be sure I procedure for failover was:

Switch(config-stack)# initiate failover

Unfortunately problem still exist.
