Hi Larry,

Thanks for your reply: this has solved my problem!

I did this, and restarted the poller by hand. It outputed loads of data
(because things were still in debug mode). A lot of my data has been
rescued, but unfortunately I ran into the 5 minute run-time limit of the
poller, and quite a bit of my data for the last 4 days has been lost,
alas: poller_output is now empty. And it looks like I need to run the
de-spiker on quite a few graphs.


Question:

Was this problem caused by the network outage in some way (e.g. polls
taking longer than normal) or is this something that happens to every
installation? Will the memory requirements keep growing in time, or only
as I add more hosts? Did I miss this in the installation guide?
Some 'php out of memory error' would really have helped in debugging
this, by the way.
