URGENT: Sensors hang after update to 4.1.1S47(48)!

[DSmirnov]

I have my sensors hang every one-two days. Started to happened after upgrade to 4.1.1S37. The only workaround is to power-cycle/reset to a sensor!

Is anyone else observe the same?

Thank you Dmitri and Robert.

For Dmitri's sensor, let us watch his memory usage

and the 'sh in gr' stat of TCP queued to see if the

TCP queue growth problem happens there.

Robert, your memory situation does sound serious and

the TCP queued should NOT be staying around for more than a couple minutes. Just a quick note: the memory

status reported by 'sh ver' is not very accurate. It

does not show the main/cached/swap values that are important to determine the real memory usage. We use the service account tool 'top' for this.

Robert, please email me directly at kasper@cisco.com

and include your TAC contact CC'ed on the mail.

We will keep pressing on looking into these possible

bug areas.

I have the exact same problem. I can ping the device which is a 4230-FE. I cannot telnet or access the device at the console. The monitor is blank and not sleeping. I am in the process of upgrading the sensors from the old 2.5(S0).

Hi,

We have an engineering build we are distributing

on a case-by-case basis. It is a patch for sensorApp

with several defects fixed. It is running at

several sites and is operating correctly.

I can make this available to you.

Please open a TAC case and send me the case number

and your contact information to kasper@cisco.com

I will give you the download and install instructions.

Online this weekend.
