Hi, First, apologies I dont have any extra information - that is partly what my post is about. I have been getting a couple of messages I have not seen before running -CURRENT, and wanted to ask whether there are any steps I could take to help debugging if people think that is worth tying. This is what I have seen over the past few days: 1) kernel: memoery modified after free and then what appears to be a memory address I saw another post mentioning a console message like this that appeared to be related to the subsequent panic, but mine hasnt caused the machine to panic. I am not sure if this is because I have the standard -CURRENT GENERIC kernel running (with WITNESS, INVARIANTS still enabled), but a reply said use memgaurd to track down the issue. How should I configure this? 2) a swap_pager message about not being able to allocate any more space. My /usr filesystem was full (except for the last 8% reserved for root only), and I had been doing some heavy ports tree compiling. I am just not sure if that message is normal and that swap was REALLY 100% used up, or whether it was indicative of something else and I should try to replicate the issue. Again, apologies if this post seems very sparse...I have very little idea where to go with these things. Thanks for your patience, Alex J Burke.
