Cisco Cisco MDS 9000 SAN-OS Software Release 1.0 Release Notes

SANTap or iSAPI processes might fail on the Cisco MDS 9222i switch when the system runs into a low 
memory condition. The kernel ends the processes due to a lack of memory. 

Because the MDS 9222i switch runs supervisor processes as well intelligent processes, memory 
utilization is high. In addition, debug files and core files that are saved locally can result in low memory 
resources. When low memory conditions occur, you might see a syslog message like the following on 
the supervisor before the processes are ended: 

"MEMORY_ALERT: Memory Status Alert : SEVERE.  Usage 90% of Available Memory"

There are two ways you can work around this issue:

Whenever there is a log or tech support collection, immediately copy the files that need to be saved 
to other servers and clean up the local file on the MDS 9222i switch to free up space.

Save all core files on other servers and immediately clear or delete the local copies on MDS 9222i 
switch to free up space.

Before upgrading your SSI image, refer to the
