I get this nice error on a switch once every hour.
Switch type is WS-C2960S-48-TD-L, Software version 15.0(2)SE4.
Any idea what it means or what I can do to fix it (cant't restart it now!)?
Google has no results.

The missing y in the last 3 lines is a copy and paste error. Sorry about that.

I just got this problem after upgrading IOS on my switch. It appears after 1 hour.
Anybody know about a solutuion?
12-11-2015 12:58 AM
We use this model when we have had these problems: WS-C2960S-48FPS-L
Current used IOS (without problems!):
c2960s-universalk9-mz.152-2.E1.bin
Used IOS durinng these errors/messages occured:
c2960s-universalk9-mz.152-2.E.bin
Probably it helps further...?!?

Hi,
It seems to be a bug. Open a TAC case for DDTS # and SW recommendation.
Kind Regards,
Ivan

I have SCOURED the internet for information on this, no luck... unfortunately service contract expired or I'd definitely open a TAC case. Anyone???

I've ran into this bug after trying to generate a 1024 bit RSA key on a 2960C after installing c2960c405-universalk9-tar.150-2.SE9.tar.
Has anybody found a fix yet?
12-14-2015 12:01 PM
Here the same. Upgraded an 2960S Stack with two members to c2960s-universalk9-tar.150-2.SE9.tar and then ssh dont work any more. On console i see these nice log messages.

Dec 14 20:47:58.493 MET: %ENTROPY-0-ENTROPY_ERROR: Unable to collect sufficient entropy (Switch 2)
Now i will try the 15.2.2.E3

I ran into this exact issue with c2960s-universalk9-mz.150-2.SE9.bin. Upgrading from this 15.0.2 image to 15.2.2E3 resolved the issue.
