I received by Extreme Networks:
Linux kernel versions from 2.6.26 to 3.3 (inclusive) are vulnerable to a deadlock condition in the handling of leap second adjustments provided provided through NTP. The next leap second adjustment is going to occur on June 30th, 2015, and there is potential for this to cause Linux-based Extreme Networks products to crash/hang.
What is a leap second ? http://www.nist.gov/pml/div688/leapseconds.cfm
I would ask this question specifically for the "C" and "S" series switches. Are they affected and where will this information be published. June 30 is quickly approaching and plans for upgrades or possible outages needs to be put in place as early as possible.
thnks in advance
Switches running SNTP aren't subject to this issue because leap seconds don't receive special handling under the SNTP protocol.
For Extreme product vulnerability and recommendations, please view: http://learn.extremenetworks.com/rs/extreme/images/VN-2015-002-Leap_Second.pdf
The above query has been taken care in the below-mentioned thread.
