[Linux-cluster] D Apache processes

[Duncan Morgan]

Hello,

We have apache running on 14 GFS nodes where the web roots are shared
via GFS. Occasionally we see that the load on all nodes rises
dramatically (to 150+) and all httpd processes become dead (D). I know
this is a little lacking in details but does anyone have any insight
into this? We suspected perhaps a cron job was running simultaneously
against the GFS file system on all nodes but have virtually ruled this
out.

Please help - this is very alarming.

Thanks in advance,
Duncan Morgan
