Hi,
On a production application (Tomcat 4.1.18/JDK-1.4.1_01) we have an
intermittant error which leaves Tomcat in a state where it does not serve
our homepage (bouncing Tomcat fixes the problem). The Tomcat log contains
the following error below. It looks to me like there is a problem accessing
a Tomcat log file but I am just guessing. The error appears in the
4teus_log.txt - as defined:
<Host name="localhost" debug="0" appBase="webapps" unpackWARs="true"
autoDeploy="true">
<Valve className="org.apache.catalina.valves.AccessLogValve"
directory="logs" prefix="4teus_access_log." suffix=".txt"
pattern="common"/>
<Logger className="org.apache.catalina.logger.FileLogger"
directory="logs" prefix="4teus_log." suffix=".txt"
timestamp="true"/>
<!-- Tomcat Root Context -->
<Context path="" docBase="" debug="0"/>
</Host>
Has anybody seen this before or can point me in the right direction to solve
this.
many thanks
Dan
