Ok, postscript: I haven't seen the problem occur in the week since making the change. Memory usage on the box hasn't really changed at all, but the error messages and the symptom have ceased and performance is still great so currently looks like case closed, thankyou!<br>

Yes, I've grabbed the mrtgs for memory usage, and at about 9:30am yesterday free ram plummeted on the box, and cleared itself up at about 12:30 or shortly before I started looking at it. There are a few times a day when free memory gets very low, but they don't correlate with cron jobs...<br>
<br>I've tried tuning the following parameters in apache:<br><br>
<p class="MsoNormal"><span style="font-size:10.0pt">
MaxClients 50</span></p>
<p class="MsoNormal"><span style="font-size:10.0pt"> MaxRequestsPerChild 10000</span></p>
<br>dropping from 150, 0 respectively. The server doesn't host any high volume / usage sites and spends most of it's day counting sheep so I'd rather the (presumably) extra memory allocated per child and auto-cycling children in case of memory leaks. I'll watch this for a few days and see how memory usage on the box compares then report back.<br>
