[Dxspider-support] System is I/O bound again

[Michael Walker]

Hi Dirk

It appears to be operating normally now after a reboot.

grep -ir convkep /var/log

produces no output.  I also had previously renamed convkep.pl to something
so it would not execute.  I assume this matches with the fact that it did
not execute.

I can include the output from the rest if you like.

Again, many thanks for your help.

Mike
