Wildcat,
To allow the provision of assistance, more detail would be beneficial. Such as the detail of your system configuration:
- which release of tools 8.96;
- the version of JDE-eg 8.10, 8.11 sp 1, 8.12;
- your enterprise server platform and database;
- delivery of the system to users-web, fat client, citrix etc;
- if applicable, your web server configuration and versions of web enabling software-eg IBM HTTP, Websphere).
Also the text (or screen prints) of the error(s) you are receiving, a description of the actions etc that lead up to the errors, where is the error occuring (fat client, web etc) and if possible any logs that are available. How old is the installation? Were there any changes made to the system prior to these problems occuring - even if they seem unrelated?
As you mention, such random errors can be very difficult to diagnose and fix, so the more information that can be sourced, the better.
