User proc uses all RAM+swap = kernel panic - shouldn't OS not allow?

2012-09-13 Thread Winnie Lacesso
Greetings, Several times over past few years I've seen user processes go mad (programming error) use all RAM, then all swap (as ganglia so vividly shows), then the box ends up at a kernel panic. (Server OS is SL5.x 64-bit BTW) What's puzzling is, shouldn't the OS by default not allow users to

I solved the problem. Stephen put me on the right track. Turns out my PATH got messed up and was calling the wrong ps. I will go hang my head in shame. -Original Message- From: owner-scientific-linux-us...@listserv.fnal.gov [mailto:owner-scientific-linux-us...@listserv.fnal.gov] On

ntop for EL6

Hi, list I've created some ntop (5.0-2) RPMs for EL6[1] and I have plans to submit it to RPMForge, but, before I do so, I'd like to test it. I'd love if the network administration guys here could give it a try and send me some feedback. Thank you [1] - http://upload.lonelyspooky.com/rpm/EL6/

Hello, Volker I'm already a Fedora packager (not an experient one) and I'd love to put ntop in EPEL (it is in EPEL for EL5). The problem in maintain ntop in EPEL6 is that Fedora now uses systemd to manage our services instead of sysv. It is a Fedora policy to keep only one spec file and that

Hi, zxq9 It is nice to have you here! =) Just find a BZ entry [1] proposing a new spec file to build in EL6 too. I'll contact the maintainer and see what I can do to help. [1] - https://bugzilla.redhat.com/show_bug.cgi?id=845195   -- Henrique LonelySpooky Junior http://about.me/henriquejunior
