kernel level errors
 

Hi,

There are two linux machines with kernel version kernel-2.4.2-2 which are used for voice application, one machine is responsible for routing and other one is having sybase db. We are getting following errors on routing machine. Can anyone let us know what these errors are indicating and how can we resolve this?

Found this on Sybase:

The following error may be seen in the ASE log: "Error 120510: ksmask__rpacket: Invalid tdslength value < length > ". This is usually caused when a non-TDS client connects to the port that ASE is using as its master listener, and sends data that is not in valid TDS format. An additional message will now accompany this message providing the IP address of the client in question, so that it can be tracked down. In addition, traceflag 7845 can be used to suppress these messages if they cause a nuisance.

kernel level errors
 

so this is purely sybase db error or is there any possiblity that it can be due to any network issue between both linux machines.
