I've lot of diskspace, where is problem ? minimum disk space is 0,001 gb

But did you enter that in the website preferences with the comma as shown above or with a decimal point? If you used a comma I'm wondering if the system has actually parsed your setting as 1 gb rather than 0.001 gb.

Use no more than 12 GB disk
)
Use no more than 12 GB disk space
Leave at least 0.1 GB disk space free
Use no more than 90% of total disk space
Write to disk at most every 360 seconds
Use no more than 90% of total virtual memory
This works for me.....

Here's what's in the database for you:
disk_max_used_gb 100
disk_max_used_pct 50
disk_min_free_gb 0.001
venue name="home"
disk_max_used_gb 1
disk_max_used_pct 50
disk_min_free_gb 0.01
I don't see the problem here: it looks like you have settings of 1 MB free, and 10MB free at home. But perhaps you have changed your settings recently...

Bruce, What does the host
)
Bruce,
What does the host record show for free disk space? Thats hostid 381903. The computer summary page shows the host has 255.49MB RAM, the message log shows the host has 191.55MB so somethings messed up.
Could be the scheduler is using old data already on the server and ignoring the newer data sent by the client.
From the message log, the host has:
191.55 MB RAM
691.70 MB SWAP
54.99 GB total disk space
2.38 GB available disk space
Is that what the server shows?

Don't confuse disk space and RAM. The database for this host currently shows:
Memory 255.49 MB
Cache 976.56 KB
Swap Space 748.15 MB
Total Disk Space 54.99 GB
Free Disk Space 0.05 GB
Looking at the scheduler-side code to calculate disk space required, something looks odd (messed up). I think David and/or Rom might have messed with this code recently. I'll have to take a good look at it. I would not be surprised if this were a bug on the server side.

RE: RE: Bruce, What

I'm not confusing disk space and RAM, my numbers came from the log included in the original message, the line "Memory inventory:". Thats followed by a line with "Disk Inventory".
Your numbers are the same as shown on the "Computer Summary" page, and not the same as the host currently has. Free disk is around 50MB, not the 2.38 reported by the host.
That summary page also shows an old host was merged. The host was created on July 28, but theres a result dating back to July 21. Perhaps the host data was taken from that old host, overwriting whatever the "current" record already had.
The new host probably came from installing BOINC 4.72. Thats what the current log shows, the result shows the old host ran BOINC 4.71.

fatbozz,
Take a look at the file "sched_request_einstein.phys.uwm.edu.xml", that has the data sent to the scheduler. What does it show for these tags:

in the section:
Don't copy the whole thing to a reply, theres a couple of "private" fields that should be kept private. And if you copy just the requested info, change the symbols to something else, like square brackets.
Thanks, Walt.

This host is currently showing (in the database)
d_total: 59048460288
d_free: 49283072
The last number is the problem. Free space is 49MB. User prefs are to leave available 10MB of free space. Hence total available space for BOINC to use on this machine is 39MB, which is not enough. The actual message to the user is wrong. But the fundamental issue here is that the host reports it only has 49MB of free disk space.
[EDIT 30 MINUTES LATER]
I have found/fixed the bug in the scheduler. The problem was with the MESSAGE sent to the user. Unfortunately I can't put the new scheduler in place. There have been a number of recent (untested) changes that David Anderson has checked in and I am afraid to put a new scheduler in place just now.
The bug was the following. The message to the user SHOULD have read:
Not enough disk space (only 39.3 MB free for BOINC to use).

BOINC 4.7x isn't picking up the host info, its just using whatever is already in the client_state file. BOINC does report 2.38GB free when it starts, but afterwards still thinks theres only 49MB available. I reported it on the developers list and opened a bug on BoincZilla.
BOINC 4.45 doesn't have this problem so reinstalling that would "fix" it, with BOINC reporting the correct free space and allowing work to be downloaded.

OK, I understand. If this doesn't get addressed reasonably soon, I'll write to David and Rom about it too. (PS: Walt, if you send me a patch against BOINC CVS HEAD, I'll apply it.)
