04:51 < rusty> m-schmoock: Thanks for bug report.  BTW, just saw this, does it effect you? https://twitter.com/kernellogger/status/1140149670259372032?s=20 
05:01 < m-schmoock> not encountered corruption yet. will check
05:01 < m-schmoock> rusty: I also noticed two problems with gossip and the routing engine
05:03 < m-schmoock> when actually using the daemon on mainnet over a longer period, it may happen that cln is not recognizing fee updates of its peers, leading to INSUFFICIENT_FEE errors. Restart helps, but thats not nice. Secondly the routing engine seem to encounter "Could not find route" where it should find a route
05:03 < m-schmoock> both problems are not really predictable which is why I have not brought it up yet
05:04 < m-schmoock> on the second one im not sure, maybe the routing engine has good reason to not find particular routes
05:05 < m-schmoock> But the first one is straight forward... keep the daemon running some time. LN-BIG is doing fee updates occasionally. try to rebalance the channel, it can fail because of wrong fees

05:06 -!- queip [~queip@unaffiliated/rezurus] has quit [Ping timeout: 244 seconds]
05:06 < m-schmoock> which is strange, as rebalance takes current feerate from gossip and is not storing this information in the plugin

05:14 < m-schmoock> re
05:19 < m-schmoock> rusty: now I may have trouble... my daemon crashed with "lightningd(3013): wallet_htlc_update: database is locke"
05:19 -!- rusty [~rusty@pdpc/supporter/bronze/rusty] has quit [Ping timeout: 258 seconds]
05:30 < m-schmoock> cdecker: when cln crashes with "wallet_htlc_update: database is locked", is this critical? what is the recommended action? Closing the affected channel? Doing another payment (if possible after restart)? Why is the SQLite database locked in the first place?? in the end its a file
05:32 < m-schmoock> after restart I used the affected channel successfully, does that mean I am fine from now on?
05:57 -!- takinbo [sid19838@gateway/web/irccloud.com/x-khjxhymesieoomuc] has joined #c-lightning
06:02 <@cdecker> m-schmoock: that means that another process has locked the database. That is not allowed by sqlite3 hence the crash
06:02 <@cdecker> Do you have something that accesses the DB outside of cln?
06:02 < m-schmoock> nope
06:03 < m-schmoock> cdecker: should I worry about this incident?
06:05 <@cdecker> Hm, if you don't know what the second process is then that's troubling
06:05 <@cdecker> Maybe `lsof` has more details?
06:05 < m-schmoock> The daemon runs normal now
06:06 <@cdecker> It happened a few times to me that a plugin reached around directly into the DB and that'd cause lock-contention with cln itself
06:07 <@cdecker> Best to keep an eye on it and see if it happens again
06:07 < m-schmoock> okay, so is there no problems with my channel funds being in danger because my db has an invalid state?
06:09 <@cdecker> No, we always commit to the DB first before any dangerous transition, so your DB will reflect the latest state
06:10 < m-schmoock> ok, thx
06:10 <@cdecker> This was done to allow arbitrary crashes at any point during the execution, DB lock contention just being one of the possible cases.
06:13 < m-schmoock> good to know :D

15:29 < rusty> m-schmoock: you have all the fun, it seems!  I'm going to deliberately connect my node to all those peers you have, to check if it's something about your gossip pattern.  The other mitigations are to abandon the store at startup if it's corrupt, and to only compact at startup.  I think I'll push those today, at least for the next release.  Then I'll produce a special branch for you with extra logging...
