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

[Dirk Koopman]

Something, somewhere is starting one or convkeps.pl commands. (I am 
presuming that the ps aux you put up on your last email on this subject 
is contemporaneous with the top you sent).

First, reboot. then, as root, do:

1. check that it is behaving normally.

2. grep -ir convkep /var/log

if nothing seen

3. cd /spider; grep -ir convkep .

If nothing is found.

4. grep -ir convkep /var/spool/cron

It has to be started somewhere and we have now covered all the likely 
"normal" places.

5. grep -ir convkep /

We now start looking of abnormal places, which will take a while...

Please let me know.
