OK. Thanks. I will limit myself properly. Yes I got those "exhausted" errors. I also have found *.emerg: * in syslog, which I think blocked all possible consoles with emergency messages like "cannot find free page" or something. So, kernel couldnt swap and starts telling me that. Now at least, I hope, next time I can get one free console and kill those big programs, before restarting. Sincerely, Marko Cehaja
