Hello all, I have got a lot of signal 11 on dmesg pid 62519 (httpd), uid 398: exited on signal 11 I am sure it is software problem, since I just moved all the things to a new servers and I still got these errors. So, I need to find the cause of the problem, but I don't know where to start. Could any one tell me what I should do first? Thanks Pang
