[Dxspider-support] Mojo Conversion, root of my troubles..

[Dirk Koopman]

Can you give me ssh access to a sudo account? You can whatsapp/signal me 
on +44 7973 333306 or on faceache messenger.

But first do: sudo dmesg

and check for sillynesses.

You *should* have the old users.v3 file left in place, as well as (a) 
user_asc. You can replace it with any users.v3, if it gone or is 
corrupted. Just run update_sysop.pl on it before you start again. I can 
supply you with one.

But I now strongly believe that there is auth/apparmor issue (or dare I 
say this some kind of VM disk I/O rate limiting) happening here.

These errors are completely new to me. They are not anything to do with 
the software which does nothing "clever" - or least - not in my stuff. 
None of these errors happen on machines I have control over. I was going 
to say that no-one has reported weird problems like this - except one: 
WA9PIE-2. He was running on Google VMs and there was all sorts of file 
corruptions going on - and yet, as a far as his users went - it was 
still working well enough for them to (largely) not notice. It turned 
out that the particular VDisk choices he had made was producing more IO 
than the $30/month VM could handle.

I put it DO's smallest droplet and it has been running (with up to 1200 
user) with no problems for over 2 years now.
