The specific error listed is:
[Warn] [logisticspipes]: Timeout on async module DeferredCoroutine{Active}@7823a7a9

The string at the end after the '@' changes every 10 seconds or so, and I'm not entirely sure what's causing the error.

I'm seeing this error on my server as well, along with very poor LP performance (extractor module with 16 speed upgrades is only pulling items once every 40-60 seconds or so). We're barely using the mod at the moment; there are fewer than half a dozen existing networks with less than a dozen nodes each.

Edit: because I'm an idiot, I didn't include the most important information the first time around: this is on LP 0.10.3.50 with the All The Mods 3 Expert pack version 1.9.0.

The actual extraction rate depends on the performance of accessing the attached inventory. The timeout was meant to identify performance problems, but those didn't occur in testing. I have increased the timeout anyway, because building our routing table also counts towards this. If it still occurs with the newest build, it should contain debug info and a stack trace. So if you still see this in your log, please open a new issue and I'll have a look then.

I have found two other problems which I fixed in de401cb. The first was the advanced extractor not correctly working and the other fixing a problem that seems to be occurring since a Kotlin standard library update and basically was wrong usage of their API. Please retest if still relevant to anyone and open a new issue when there is still a problem.
