My OS is a RHEL 5 x86_64. It has an application that receives an average of about 500 simultaneous connections. The version of SSH is the 'openssh-4.3p2-24.el5'. When someone enters the application is '├─sshd(23445)───sshd(23499)───bash(23500)───app.sh(23528)──-app.bin(23558)". I do not know the reason, the more times the connection is lost tty, the bash and app.bin 100% cpu. We "simulate" the situation with 'kill -15 23499', (pid 23499- | \_ sshd: xxx@pts/327 ). Does anyone have any idea? Suggestions? Aldrey Galindo
