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

[Rene Olsen]

Hi.

I am running Spider on a cloud server, the absolute smallest one I could get.

I think it is 1 vCPU, 512 MB RAM and 20 GB storage. What 1 vCPU is I have no clue, but 
working on the shell and the speed in spider i OK for me.

I seldomly have more than 50 users though. I have no idea what would happen if it was 10 
times that or more.

Running debian OS.

Am running DX Spider Cluster version 1.55 (build 0.181 git: 65ed61f[r]) on Linux, which I am 
sure is probably not the most recent one. I don't really recall when I last did an update.

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.

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.
