Hi,

Each morning, i have to reboot my server, as cronjobs seem to block the
whole server. Load goes up to avg of 5.46, the server of course does no
longer answer requests.

I found the following in the logs:

I know, this is quite a lot of information. The strange thing is marked
with *-->. Could this be a diskproblem or a prob of memory allocation?

Thanks for your help.
