Recent lag problems

It's rare for servers to be behind NAT, though, not to mention that both of the iPhone servers have their own IPs.

This is a physical host with a lot of virtuals. Considering the servers are listening on seperate ports, there is no major issue here. It's like one web server serving multiple websites through vhosts. Classic iPhone got a separate machine due to how intensive it got during peak times. This isn't an issue for most smaller playerworlds.

My point is that they're on the same host, hence lag problems could potentially affect them all, especially if it's a network issue.

To add a little more: some virtualization software doesn't limit resources per child, in which case even too much processing being done by one child could easily affect the others.

Even with hard limits on processing, excessive I/O done locally could also lag all the other children. However, since the boxes are rented/colocated, I wouldn't be surprised if there is also a SAN available to avoid the majority of the IO issues, but that is just speculation.

A few days ago I've restarted the Kingdoms npcserver because it was taking close to 2 GByte of memory, must have been some monster spawn or event or so?

Is it possible to add something to /memstats which gives us info about how much free memory there is, and how much is in swap? If so, developers could handle this sort of problem themselves.

There is /memstats malloc
Kingdoms takes again more than 1 GByte, for a long time it was quite stable but in the last few days it's a lot. Previously that only happened with the release of the easter quest. It shows 800 MByte of freed memory for Kingdoms.

Event masters have been spawning ridiculous amounts of monsters lately. Maybe talk to Tig and make sure they are stripped of these rights.

ouch.

those events are fun. why not try and workout a solution... instead of limiting the fun.

Monsters spawned by non-admin EMs don't give experience. It is a problem with the MUDlib, and one that needs to be fixed. EMs probably shouldn't be spawning so many monsters anyway, though.

why not?
