Logwatch kernel error what does it mean?

Logwatch is very useful

[Clark]

I've had logwatch installed for a long time. It's really great. Tells you a lot. However, I don't understand 90% of it.

For example:

WARNING: Kernel Errors Present
smb_get_length: recv error = 5...: 4Time(s)

Is that bad?

I upgraded kernel but haven't rebooted this production server yet, maybe that could cause it?

I don't know if that's really the kernel, or Samba. Samba does spit out errors like that a lot. I wouldn't worry, as long as everything's working. The only errors I really watch for are drive errors and security breaches, and this isn't either one.
