[CentOS] filesystem read only after logrotate CentOS 5

2014-02-03 Thread Helmut Drodofsky
Helo, up to 04:02 the root file system was OK. With the logrotate activities there are messages: read only. Last entry in /var/log/messages is the sendmail entry from logrotate. less /etc/mtab gives: /dev/sda1 / ext3 rw 0 0 proc /proc proc rw 0 0 sysfs /sys sysfs rw 0 0 devpts /dev/pts devpts

Virtual Machine Manager (virt-manager is the package name) is a nice and easy to use GUI for creating, modifying and deleting virtual servers on CentOS. It uses the KVM hypervisor by default, which "just works". I'd strongly recommend giving it a try. On 03/02/14 04:31 PM, Ridhwaan Mayet wrote:

You could try tunning apache.. Start with MaxRequestPerChild, whichs sets a number of requests for child process before it is stopped. When a child is stopped, memory is freed. This could be your protection before running out of memory. KeepAlive is enabled? If yes, maybe you could try disabling
