HugeAlice2, HugeAlice3 and HugeAlice4 all show that the transaction is part of the chain:

I trust nodes in the network more than any explorer.

@CryptoBeliever @BloodyRookie

The node in the server which Exploer deployed:
http://explorer.nemtool.com:7890/transaction/get?hash=dd94394757a6d5f6ea2f38432513fca8c8813ba0626d41cf444990515d2f0317 (no result)

Some Supernodes:
http://213.252.247.126:7890/transaction/get?hash=dd94394757a6d5f6ea2f38432513fca8c8813ba0626d41cf444990515d2f0317 (no result)

http://45.32.254.135:7890/transaction/get?hash=dd94394757a6d5f6ea2f38432513fca8c8813ba0626d41cf444990515d2f0317 (exist)

So, the NIS need more RAM？

@gd_kuaile

I think http://213.252.247.126:789 is a different thing. In my opinion it has default hash retention time (config.properties) which is shorter than this transaction creation time.
For example this transaction: http://213.252.247.126:7890/transaction/get?hash=df1067b5bedeb8b48bfc4c83c5723e2cb57747c692058462d7c823f455f1511a is not returned too because it’s too old. Hash retention time should be -1 if we want infinity.

Hi @CryptoBeliever
Thanks for your answer.

Hi @CryptoBeliever
Updated yesterday, seems work fine, thanks.

Hi @garm
This bug will be fixed in next update, but it may take quite a long time, maybe 3 or 4 weeks, thanks.

Hi,
The explorer will be moved to new server in 48 hours, it will be down for a short while, thanks.

Hello @gd_kuaile would be possible check why this transaction is not visible in explorer?

https://explorer.nemtool.com/#/s_tx?hash=83639e2699096fd827a4223f825fe701514ef5a67aab488072323ba21f1e8d36

It’s visible in second explorer:
http://chain.nem.ninja/#/search/83639e2699096fd827a4223f825fe701514ef5a67aab488072323ba21f1e8d36
and returned by nodes:
http://hugealice3.nem.ninja:7890/transaction/get?hash=83639e2699096fd827a4223f825fe701514ef5a67aab488072323ba21f1e8d36

Hi @gd_kuaile. I think explorer has some problems with missing transactions. It’s not the first time.
Today’s example:

http://hugealice3.nem.ninja:7890/transaction/get?hash=1f14280717be7ce0ee510cd81139accde77ef836aec576c9708fd44f97f74db9 (returned)

NEM - BlockChain Explorer (not found)

Hi @CryptoBeliever ,
I am investigating the problem and testing, it will take some time, thanks.

@gd_kuaile could you check explorer? Seems not working.

#77

Hi, sorry, the server was rebooted and i did not know that. NIS is booting now, after that the explorer will be started.

Hi @CryptoBeliever @BloodyRookie

For the API ‘/local/chain/blocks-after’ from NIS, it returns different results at different times.

For example, from my local node

It rarely happens, is this normal?

Thanks.

#79

Here is my testing program, keep running the program for some hours, it will output the message.

#80

Maybe it was due to a rollback. Small rollbacks (1-2 blocks) do happen.

#81

Thanks.

Looks like explorer is very slow. Problem with NIS?

Hello,

How explorers are able to get those namespace’s details which are expired? I tried from API but its giving me empty data if that namespace is no longer in use/expired.
