This is just a quick tip for those on JDE tools release 188.8.131.52.
For the past few weeks we have had lot of fun with zombie kernels on the windows App Server. We would see zombies first thing in the morning, when there are absolutely minimum load on the server, and also when there are 100 users logged in. It would be extremely difficult to track down a process that causes Zombie kernels, as the logs will have different information at different instances..
All along I have had three new logging features enabled on the windows app server. The settings in JDE.INI in question are –
By default these are expected to have value of FALSE. With these settings enabled, you will receive messages in the log files like ‘Unterminated cache’ etc. If for troubleshooting issues you enable these flags be cautious, as they would cause Zombie call object kernels.
As soon as we disabled these flags, to remove unwanted messages from JDE logs, zombies disappeared!
We have reported this to Oracle and waiting to hear from Development.
