In R12.52 SP1 CR05, we encounter a 500 error after shutting down LLAWP process by using "kill -9" on the Apache WebServer.
In R12.0, the behaviour is different. We do not have a 500 error, because LLAWP restarts properly.
The current behavior in 12.52 is due to a bug which seems to have gotten introduced in 12.52SP1. Due to this bug if the LLAWP process gets killed without a clean shutdown, its process id remains in memory.
This issue will be fixed in 12.52SP1CR07 (Planned for Q2).
Thank you for sharing this tip with the community Julien!
