Hi All
I have sent this to the general group but received no response. I hope one
of the developers out there can help.
I have a cluster of 8 nodes all running mosix on a 2.4.26 Gentoo Kernel.
There is a master node from which all commands are executed and NFS is
running on all the nodes. We have a python script running which is causing
the above error but only after hours of running it. At this point the nodes
start to drop off with a panic, one by one over time
"mosix_update_remote_files: not listed". We have noticed that a file that
should have been created by the script appears to be missing. The script has
executed this piece of code thousands of times while it has been running and
we have put checks in to be sure that the file exists before using it later.
Can anyone enlighten me on what this function does and possible reasons we
might get this error? I am not sure at this point if it is a bug with Mosix
or with the script itself. One other point, the master node from which the
script is executed does not seem to fall over which makes me think that the
problem is with Mosix rather than the script.
Thanks
Dave Toomey
