I have a linux OES box which was importing machine perfectly into the tree. I few security patches where applied to the OES box except the Kernal Patch and
i now get the following error in the awsi.log

javax.naming.Communication Exception: localhost 636 [Root exception is java.net.ConnectException : Connection Refused]

Which means nothing imports.
If you run zwsreg -importserver server manually it report backs
No import policy Found

One is configured but i believe the service is not login into the tree
to find it.

Patches applied up to date on the 30th Sept

vsftpd 2.0.4-0.5
jakarta-tomcat 5.0.19-29.16
java2 1.4.2-129.4.3
java2jre 1.4.2-129.43
libtiff 2.6.7-28.14
opensc 0.8.0-194.6
perl 5.83-32.14
apache2-jakarta-tomcat-connectors 5.0.19-29.16

SSL is not configured on the server, No TLS and no SSL Enabled.

I believe it something to do with the java patches.
