Have you tried to add the -DdisableLuceneLocks=true flag to the RUNJAVA
command of catalina.sh? I had to add it to run servlets accessing lucene,
but
I'm not sure what my problem was.
Lines 219-227 of my catalina.sh (running jakarta tomcat 5.0.16 under linux):
else
"$_RUNJAVA" $JAVA_OPTS $CATALINA_OPTS \
-Djava.endorsed.dirs="$JAVA_ENDORSED_DIRS" -classpath "$CLASSPATH" \
-Dcatalina.base="$CATALINA_BASE" \
-Dcatalina.home="$CATALINA_HOME" \
-Djava.io.tmpdir="$CATALINA_TMPDIR" \
-DdisableLuceneLocks=true \
org.apache.catalina.startup.Bootstrap "$@" start \
>> "$CATALINA_BASE"/logs/catalina.out 2>&1 &
