Hi all, I have two servers both identical in hardware and I have just done a clean install of CentOS 5.2 x86_64 on both. Sometimes (more often than not) when I log in at the physical console (e.g. tty1, tty2, etc.) I will be logged in and it stops responding even if the shell is not doing anything. When this happens I can still switch to another VT with alt+f2 and login as normal. I don't know if bash, mingetty or whatever process is locking up. If I do a `ps ax` all processes are sleeping. Any idea's what could cause this? Thanks

If II assume that you''ve tried typing <Ctl+Q> -- just in case of flow control, yes/no? -rak-
