Erlang shell crash
Fri Jun 9 09:32:32 CEST 2006
I'm using Eralng emulator version is 5.4.3.
The type of application is load testing with simulator in one PC ( which has
multiple thread. At that monent we have 200 threads) which sends requests to
the server in another PC.
The Shell running as server is collapsed.
