Symptom: Fibre Channel links with traffic running on it might generate syslog errors such as the
following:
2008 May 21 15:08:55 switch %KERN-3-SYSTEM_MSG: FCP_ERRFCP_PORT:
gat_fcp_isr_process_blk_intr@1441, jiffies = 0xb1cec:ISR threshold reached, reg_block
= 0x8, num_regs = 6, idx = 0, src_bit = 11 - kernel
There is no loss in functionality and these messages can be ignored.
Workaround: None.

Symptom: One global MAC address is used in all STP and PVRST frames originating on various
ports. This can result in inconsistent MAC moves on peer switches connected with multiple links.
Workaround: None.

Symptom: Ethernet port channels configured between two Cisco Nexus 5000Series switches cause
a memory leak in the DCBX process. This leak eventually leads to the DCBX process crashing and
a system reboot (in a few days). This issue occurs only with Ethernet port channels between Cisco
Nexus 5000 Series switches. Port channels using the Catalyst 6500 Series switches do not have this
problem.
Workaround: Disable receive and transmit Link Layer Discovery Protocol (LLDP) on the port
channel members by entering the following configuration under each Ethernet interface that is a
member of the port channel:
Interface Ethernet 1/1
no lldp receive
no lldp transmit
CSCsq36609
Symptom: For a virtual Ethernet or virtual Fibre Channel interface configured as a SPAN source,
changing the interface administrative state results in a memory leak. Deleting and adding SPAN
sessions also causes memory leaks. The memory leaks eventually cause a switch reboot.
Workaround: Avoid using virtual Ethernet and virtual Fibre Channel interfaces as SPAN sources.
Avoid deleting and adding SPAN sessions.
