The below are the env details of our production system:
Apache Proxy: 2.2.11
Apache Tomcat: 5.0.30
JDK: 1.5.0_15
=A0
With JDK 1.4.2_15 on development, I could resolve this by adding request.re=
gisterRequests=3D"false" in $TOMCAT_HOME/conf/jk2.properties. When applied =
the same to JDK 1.5.0_15, I am getting the below errors repeatedly before r=
esulting in "OutOfMemoryError". Since it is production issue, could you ple=
ase=A0provide a solution for JDK 1.5.0_15 ASAP?=A0Let me know if you need a=
ny details.
