We just plugged in a test box this morning. Our Netcache reboots almost every other day now due to memory leaks
Guess I must be lucky. Most common uptime is 3 weeks (when we last installed new software) and the boxes run at 80%+ load for 5-12 hours/day.
Just for another data point -- we have two C760 caches, running 3.3.1 and 3.3R2P1 in web accellerator mode. We have to manually reboot each box every couple of days. We sustain 98-100% CPU utilization almost 24/7, run each cache at near 100BT wire-speed for 18-hour-long peaks, but run into situations where caches will suddenly drop to only 20Mb/s out.
In the past we've had problems with max open file descriptors, but this doesn't seem to be the case currently.
We're actively working with NetApp to address these stability issues. Overall I'm pleased with what the C760 is able to deliver, we absolutely hammer them.
