Hi, We are running into an issue where users are unable to login to the RHEL 4.7 machine even via console. Both username and password are accepted, and then after a while users are returned to the login prompt
Here is my "theory" : I suspect that this may be the case of Process Table overflow, where OS is unable to create a new process. In order to login the user, after password verification, OS needs to provide an interactive shell to the user If the Process Table is full, no new process can be created including a shell. But all the existing processes would continue to run - hence the login prompt. Query: 1. How do I prove or disprove my theory ? The big problem is that I can't get "into" the system to troubleshoot, and the problem goes away after a reboot. 2. How do I "catch" a rogue process (which may be forking too many processes resulting into PT overflow) 3. How do I prevent this from happening in future ?
