[Dxspider-support] Help needed - still unable to save user_asc files

[Dirk Koopman]

More than once, probably about six times.

One can rebuild the user file and restart the node. All is then well for 
a while. I believe I have seen it work for more than one week, but 
within another week or two it will revert to an empty user file. It MAY 
be related to spawned jobs which write to the user file thus corrupting 
the user file, but not every time and, in any case, I can't see any 
spawn jobs that might do a write. I am reluctant to put in file spin 
locks but it may become necessary. It MIGHT be memory usage, but there 
is no objective evidence for a lack thereof.

Mike seems to have the only instance of "standard" (i.e. non-mojo) 
DXSpider that can (at least for a time) support 1000+ users on quite a 
lowly single processor GCloud instance - and seemingly with room for 
many more. As you know Ian, us lesser mortals start to see serious CPU 
usage above about 4-500 users (depending on processor). And worse, it 
appears that the mojo branch runs like a snail on mogodon on an 
identical instance in the same data centre. Which is the exact opposite 
of anyone else's experience.

Mike is unwilling to run his node on dedicated hardware for perfectly 
reasonable reasons. But otherwise, I am stumped.
