Lag issues on pollNextZones

Recommended Posts

Not sure what's causing it, had a fairly large lag spike on the server today 4k map, 40k creatures, 5gb ram, only using like 2gb max over any period of time. I've installed Friya's server debug mod thinking I would understand the output, but I really don't. :) Any help would be appreciated.

Most likely caused by damged being calculated for decay on large quanties of items let on the ground, rocks, logs, and other abandoned skilling materials.

Won't it tell me where it's located? I've seen in the past logs that have zones.Zone XPOS, YPOS polled X tiles took X.XXX ms, etc. My logs contain no such data it's just this very generic pollnextzones(0.5) and it occurs every 5 mins for around 1 second, but then sporadically I'll have 20-30 second lags on my server

 

Yesterday 4:21 pm EST, ~15 seconds
Yesterday 6:03 pm EST, ~30 seconds
Today 7:05 am EST, ~15 seconds
Today 12:18 pm EST ~20 seconds

 

The lag spike logs are like those in the pastebin, the every five minutes don't trigger the Friya debug server mod, but are just pollnextzone(0.5) and then lag detected. Ending up with lag counts in the thousands. I don't know if this is pretty normal for mini-lags to occur. We are on pingperfect/high cpu/SSD/5gb, but it's fairly low in resource usage.

I am not sure if any one has decoded the actual map positions from the zone information that is in the log files.

May be one of the Middle can look into the polling code to see how it handled.

Ah, what I was referring to can be found here, but my logs just stop at the : INFO com.wurmonline.server.Server: Lag detected at Zones.pollnextzones (0.5) so I wasn't sure if it is the same issue since it does not have a zone position or how many tiles it was attempting to poll.

Yeah the disablefogspiders joebadoe made didn't work after 1.9 I updated the code and put it on the server last night and am gonna let it run through a full day to see if any fog spiders get spawned, if not I'll push it out.

How would I disable fog spiders?  We've been getting terrible lag, and I'm pretty sure they are the culprit.

Or do I need to wait for a mod to come out?

I updated the mod to disable fog spiders some time ago.

Why exactly are fog spiders responsible for lag?

 

Strangely I rarely see them, even during or after fog. Not a complaint, they are useless.

Example from Sklotopolis: 470 fog spiders spawned 70 of them killed instantly and that just in 1-3 server ticks. That is not a friendly thing to do

 

Spawning has IO operations killing has IO operations, IO operations everywhere

What Sklo said. It's pretty much a lag-fest anytime they are killed off.

Maybe the error is not related to the mod. Try to start a backup and check if the server launches.
