orignal so we have found the problem

zzz ok

zzz zlatinb, thanks for the great testnet work yesterday

zlatinb np it was fun

zlatinb except for the "apt get openssl libboost-all-dev" which took forever

zzz sure I can try to find the ntcp-only problem, will put it on the list

zlatinb should have done it in the first container before the cloning :)

zzz I see an i2pd checkin last night, is that the fix?

zlatinb yeah, verified

zzz as in tested on the testnet?

zlatinb out of ~600 tests only 1 failed, I didn't bother investigating it

zlatinb yes

zzz so it's an SSU problem?

zlatinb looks like it; I imagine it renders the object pool foobared

zlatinb but I know next to nothing about std and boost

zzz is this object pool isolated to SSU or it foobars the whole router?

zlatinb idk

zzz need to know how to avoid the problem from our side

zlatinb need a working ntcp-only testnet for that lol

zzz orignal, how can we work around it?

orignal zzz give the priority to NTCP2

orignal basically SSU dropped too many packets

orignal that's was the rpoblem

orignal this pool problem is specific to SSU

orignal how we merge fragments

orignal I will rewrite it later

zzz what versions have the problem?

orignal 0.9.52

zzz only?

orignal yes

zzz ok

orignal I tried to optimize memory usage for it

zzz so nothing about STBM or anything like that, it's just an SSU thing?

orignal basically I copied code working well for NTCP2 to SSU

orignal but SSU works differentyl due the fragments

orignal it's only SSU thing

orignal packet drops

orignal maybe there is something else

orignal but zlatinb doesn't see any issues in testnet after this change

zzz sure, there always could be more bugs ))

orignal and ofc I didn't see any problem with that routers from the list because I used NTCP2

zzz good job finding it

orignal for 1 hop

orignal this job is not done yet

orignal because I need to find out what exatcly wrong in SSU with fragments

orignal maybe there is one more old bug

orignal but it doesn't affect functionality

zzz ok

orignal but also I see another issue

zzz I can use NTCP2 only for connections to i2pd 0.9.52

orignal no, never mind

orignal yes, it would be nice

zzz but maybe should also avoid i2pd 0.9.52 in tunnels

orignal up to you

zzz do you plan to do a release soon to fix it?

orignal no. let's wait for regular release

orignal also you might use 0.9.52 in tunnels if they are connected trough NTCP2

orignal I don't know if you have the code for it

zzz do you know how many SSU packets are being dropped? about what % ?

zzz yeah but I don't know how the 2nd and 3rd hops are connected

orignal I would day 1/20

zzz me either, will have to look

orignal *say

orignal also remember that i2pd always prefer NTCP2

zzz do things get corrupted and it starts dropping everything? or it's just random?

orignal if possible

orignal random

zlatinb I didn't count but eyeballing before the fix about 40-50% of the java tunnel tests failed

zzz ok

orignal it's not corrupted compeletely

zzz we were going to release on feb. 28 but we could probably do it on the 21st instead

orignal just override some start of buffer for some packets

zzz whats the earliest you could release?

orignal most likely by multi-fragments

orignal I need to ask R4SAS

orignal if he is not busy

zzz I think 21st is the earliest we could do it

orignal I can do at any time

orignal 21st is fine

orignal also it affects to data messages only

orignal and not like peer tests, etc.

orignal also Tunnel creation success rate: 73%

orignal after rebuild on some VPS

zzz but you could go before us

orignal I want to mark it as 0.9.53

orignal maybe few days before yes

orignal but not more

zzz ok

zzz workarounds tested and pushed

orignal works?

orignal implemented clock skew change for NTCP2

orignal Bob sends SessionCreate now and then closes the session
