JkCoyoteHandler Error

JkCoyoteHandler Error

2004-05-06       - By Allistair Crossley

Hi All,

I have been looking through our production server logs and the following error
block is repeated an awful lot, like every 6 minutes or so and sometimes 6
times per minute.

INFO: Unknown message 0

The difficult part is that no user has reported any errors to us and I have
never seen an error arise from using the system, so I am a little puzzled at
where this is coming from and despite not having errors reveal themselves or
being reported, I still want to get to the bottom of them and remove the cause
if possible.

The system is now fairly basic:

IIS + NTLM Auth
 --> JK2
   --> Tomcat 5.0.19
     --> JNDI SQL Server port 1433
     --> Content Management System port 4444

If anyone could suggest what this error may be, why I may be getting it or how
I can go about getting better resolution on the root cause I would be very
grateful,

Cheers, Allistair.
