Posted February 28, 2019 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. https://pastebin.com/7RdfV9ge Share this post Link to post Share on other sites
Posted February 28, 2019 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. Share this post Link to post Share on other sites

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.

Posted February 28, 2019 (edited) 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. Edited February 28, 2019 by bigsteve Share this post Link to post Share on other sites

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. Quote [02:24:43 PM] INFO com.wurmonline.server.Server: Lag detected at Zones.pollnextzones (0.5): 12.184 seconds [02:24:43 PM] INFO com.wurmonline.server.Server: Elapsed time (12200ms) for this loop was more than 1 second so adding it to the lag count, which is now: 984 [02:24:58 PM] INFO com.wurmonline.server.zones.Zone: Zone at 2304, 1344 polled 54 tiles. That took 6510.884 millis. Edited February 28, 2019 by Ayluin Share this post Link to post Share on other sites
Posted March 3, 2019 Ended up being fog spiders. Disabled them and no more lag. Thanks for the assist. 1 Share this post Link to post Share on other sites

Posted June 23, 2019 How would I disable fog spiders? We've been getting terrible lag, and I'm pretty sure they are the culprit. Share this post Link to post Share on other sites

Posted June 25, 2019 Why exactly are fog spiders responsible for lag? Strangely I rarely see them, even during or after fog. Not a complaint, they are useless. Share this post Link to post Share on other sites
Posted June 25, 2019 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 1 Share this post Link to post Share on other sites
Posted June 25, 2019 What Sklo said. It's pretty much a lag-fest anytime they are killed off. Share this post Link to post Share on other sites

Maybe the error is not related to the mod. Try to start a backup and check if the server launches. Share this post Link to post Share on other sites
