    My virtal server automatically restarts...


    Hello, this is my first message. I manage a Virtual Web Server(provider Dattatec).

    uname -a:

    (...) 2.6.16-xen3_86.1_fc4 #1 SMP Thu Apr 13 08:26:52 PDT 2006 i686 i686 i386 GNU/Linux

    The problem is that the server automatically restarts... in /var/log/messages, i don't see any message:

    Sep 2 19:46:50 ybr125 sshd(pam_unix)[26519]: check pass; user unknown
    Sep 2 19:46:50 ybr125 sshd(pam_unix)[26519]: authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=218.***

    I ask mi provider, and says that is because is out of memory... How can i check this? How can i know why my server restarts ?

    Thank You!

    I can be found either 40 miles west of Chicago, in Chicago, or in a galaxy far, far away.

    Well, from the last line, it appears you have about 256M of RAM. So, does it restart after running awhile? What sort of applications, drivers, servers are you running? What other hardware do you have in the system? More info will help us provide better advice.
    Sometimes, real fast is almost as good as real time.

    Hello Rubberman, Thanks for your time.

    Yes, server has 256mb of RAM

    Disk usage is 88%(634mb Free)

    Is a Web Server(Running a phpbb forum)

    About drivers/hardware, i don't know what do you mean. This is a Virtual Server. I got the VPS installed and running.

    So, how much RAM does the host have? Can you increase the amount of RAM allocated to the virtual machine?

    Yes, it has 256mb.

    If i pay more, i can increase the RAM. But, before doing that, i want to be sure that the RAM is the problem. Is there any other Log i can check?

    There are a lot of logs in /var/log that you can check. Also, try the dmesg command to view recent messages relevant to the kernel.
