Unable to stop a jail

[Steven Hartland]

We've got a jail here which we cant stop with either killall
jexec or jkill all return success but jls still reports
the jail as running.

The machines running several other jails which I cant restart
at this time so I ended up starting the jail again jls
now reports:
jls
   JID  IP Address      Hostname   Path
     9  10.10.0.5     jail6        /usr/local/jails/jail6
     7  10.10.0.5     jail6        /usr/local/jails/jail6
     6  10.10.0.4     jail5        /usr/local/jails/jail5
     5  10.10.0.39    jail4        /usr/local/jails/jail4
     3  10.10.0.6     jail3        /usr/local/jails/jail3
     2  10.10.0.8     jail2        /usr/local/jails/jail2
     1  10.10.0.7     jail1        /usr/local/jails/jail1

Host machine is running FreeBSD-6.1-P10

Any ideas some sort of kernel data corruption?
