Choosing A Webhost:
A web hosting service is a type of Internet hosting service that allows individuals and organizations to provide their own website accessible via the World Wide Web. Web hosts are companies that provide space on a server they own for use by their clients as well as providing Internet connectivity, typically in a data center. Web hosts can also provide data center space and connectivity to the Internet for servers they do not own to be located in their data center, called colocation. more...

Recurring Zombie (XenU used as a web server): msg#00009

Recurring Zombie (XenU used as a web server) |
For some weeks I have a problem with XenU domain used as web server. It is
turning into Zombie domain:
# xm list
Name ID Mem(MiB) VCPUs State Time(s)
Domain-0 0 641 4 r----- 263.6
Zombie-wwwmain 2 512 1 ----cd 5238.4
dns 4 128 1 -b---- 20.1
intranet 6 512 1 -b---- 18.7
ldap 5 128 1 -b---- 61.4
mail 3 512 1 r----- 1078.0
www 1 512 1 -b---- 117.7
wwwextra 7 512 1 -b---- 33.2
(Both Xen0 and XenU are running FC5 with kernel 2.6.17-1.2174.)
- How can I find out what is causing this problem?
- How can I fix it / work around it / report a bug?
This is production machine so I would appriciate any pointers. I didn't have
this problem before. Maybe new kernel is causing the problem? Is there a way to
get older versions of kernel packages?
I would also like to note that when this happens networking doesn't work in ANY
XenU domain. E.g.:
# xm console dns
after login trying to ping Google IP:
# ping 72.14.221.104
PING 72.14.221.104 (72.14.221.104) 56(84) bytes of data.
ping: sendmsg: No buffer space available
ping: sendmsg: No buffer space available
ping: sendmsg: No buffer space available
...
and when I run "init 0" in XenU (e.g. in dns XenU):
# init 0
it hangs at this step: "Removing module iptables: "
When I try to shutdown XenU from Xen0 it also turns to Zombie. E.g. (dns XenU
domain turns into Zombie-dns):
# xm shutdown dns
What can I do?
