Monero GUI 0.17.1.9-release on Win 7 x64

moneromooo-monero commented 3 years ago

Are you piping anything into whatever program generates this ? Or executing it from a non shell program, that kind of thing ?

M0ns1gn0r commented 3 years ago

@moneromooo-monero

I open monero-wallet-gui.exe from Total Commander, then the GUI automatically starts the monerod.exe (I use the simple mode).

But the problem persists even if I start monero-wallet-gui.exe directly from the explorer.

M0ns1gn0r commented 3 years ago

The problem doesn't reproduce if I open the GUI client via start-low-graphics-mode.bat.

mj-xmr commented 3 years ago

I have 90 log files with only this message:

Please give a few examples of file names of the log files. I'll look into it.

M0ns1gn0r commented 3 years ago

@mj-xmr 

bitmonero.log
bitmonero.log-part-1
bitmonero.log-part-2
bitmonero.log-part-3

And so on. Then it looks like that a rolling log mechanism overrides them.

From IRC:

(selsta) usual solution is attempt to update drivers and check if issue reappears

selsta commented 3 years ago

Talking about graphics drivers

M0ns1gn0r commented 3 years ago

As I said, the issue disappears when I start the GUI from the command line. It's hard to believe that the graphics drivers can have something to do with that. But I'll give it a try.

M0ns1gn0r commented 3 years ago

Sorry, I forgot to mention, that the issue disappears not because of the "low graphics" mode, but because the GUI is started from the command line. I checked that by changing the script to: 

@echo off

start /b monero-wallet-gui.exe
selsta commented 3 years ago

Ok, sorry then I misunderstood this. Usually if things work with low graphics mode it means it is graphics drivers related but in your case it seems command line (or something else) related.

M0ns1gn0r commented 3 years ago

No problem. Maybe the problem lays in Win7 x64.

This is how the log looks like after starting the GUI:

moneromooo-monero commented 3 years ago

My guess is that Total Commander changes the new process' stdin, which causes monerod to be unable to read from it. Maybe the GUI does not start monerod with --non-interactive ?

Yep. https://github.com/monero-project/monero-gui/pull/3360
