FACT(s) (Environment):

Solaris 10
OpenEdge 10.1B03 Service Pack
All Supported Operating Systems
OpenEdge 10.1B

CAUSE:

Bug# OE00164363

CAUSE:

This is a Latch release timing bug. The application is mapped CTRL-C to CTRL-]. CTRL-] when used to release the applications access to a record rather then waiting on a locked record, would shut down the terminal session rather than allowing the application to continue.

FIX:

Upgrade to OpenEdge 10.1C01 or 10.2A and later.

If upgrade is not viable at his moment the workaround is to unmap CTRL-C in the application.
