bvt: | http://bvt-trace.net/2020/02/a-tiny-and-incomplete-trb-wedgetrace/#comment-139 - did some more debugging today, but cannot get a wedge when i do need it | [18:30] |
mp_en_viaje: | bvt, don't feel too bad, this is a massive problem owing to the insanity of the gearbox involved. the vast majority of historically observed wedges were never reproduced | [18:34] |
mp_en_viaje: | i guess in some quarters this counts for "intrinsic stability" or something, but... | [18:34] |
bvt: | well, the only thing i feel bad about in this situation is that for some time i was getting wedged in ~30 min, did not check the logs, assumed the DB corruption, rolled back to month-old chain snapshot without keeping the current | [18:37] |
mp_en_viaje: | a | [18:46] |
bvt: | anyone debug.log snapshots of wedge: did the period before wedge involve a large number of continous block requests? | [18:57] |

mod6: | bvt: Yes, I experience exactly like you describe right before 'wedge', incoming 30k or so of 'received getdata for: block' in debug.log. | [21:08] |
mod6: | I have a debug.log that is ~12G that goes back ~3 mos to block #605198, i do see those requests, but in the dozens at a time at most. but not a tidal wave of tens of thousands. | [21:12] |
mod6: | When alf alerted about this wedge on the 22nd, I was quick to point out this wave of stuff that I don't typicaly see. | [21:13] |
mod6: | Happy to provide the 12G log if you want that, or a shorter one that shows on 22nd or 23rd my node starting, then getting wedged after wave. | [21:14] |
mod6: | Apparently main.cpp:ProcessMessage() allows for quite a number of these getdata commands before flagged as 'Misbehaving'. But I've not seen waves like this before now. Quite possible I've just not seen them either tho. | [21:18] |
mod6: | http://btcbase.org/patches/genesis#L11361 (I'm sure you've already looked at this tho. But for folks following along...) | [21:20] |
mod6: | Here's that quick deebot snippit I posted on Friday night (iirc): http://paste.deedbot.org/?id=Oj7N | [21:25] |
mod6: | If others have this same type of behavior, please write in and say, show us the debug.log if you can. Thanks. | [21:41] |

mod6: | bvt: et, al. Was able to use alf's wedger tool to replicate the problem. It took exactly 1 try. Here's my notes and debug.log (renamed) from the test: http://www.mod6.net/wedger/mod6_wedger_test1.log http://www.mod6.net/wedger/trb_debug_wedgerpy_test1.log | [22:27] |
