Not getting work

(moderation:
Hi! I have just installed boinc, running e@h on my good old mac g4 1,5ghz, 512ram. It has over 25 gb of free hard disk space.
Message says: "no work sent. there was work, but not enough disk space allocated. An additional 2547 mb is needed."
What can i do to fix this problem? I have completed work earlier...
Thanks for answers.

Checking the log, I see:
disk_max_used_gb 20.000000
disk_max_used_pct 50.000000
disk_min_free_gb 30.000000
So you set your disk space for BOINC to use at 20GB, use at maximum 50% of total disk space and leave at least 30GB free.
The next line says:
host.d_total 79892103168.000000
host.d_free 27347804160.000000
host.d_boinc_used_total 35590073.000000
You used 50% of your total disk space, you need to free space for BOINC to use, or increase your 50% number and minimum disk free number.
Can you please repeat that in

Can you please repeat that in an easier way? What preferences am I supposed to change?

General Preferences.
Scroll to the bottom, Edit preferences.
Disk and memory usage part.
Change:
- Leave at least 30GB disk space free to something (a lot) smaller.
- Use at most 50% of total disk space to something higher.
Examples:
Setting the first to 0.1 means you tell it to stop pouncing you until the minimum disk space BOINC can use is 100MB.
Setting the second at 90% will give you the extra clearance that it'll only start bugging you again when you have used 90% (72GB) of your 80GB drive.
Don't forget to save the changes to the website with the button on the bottom.
Now open BOINC Manager, Advanced view, Projects tab, select Einstein@Home by clicking on it, then click Update. It'll get the new preferences in and things should start rolling again.
Great. Now it worked again.

I don't seem to be getting any new work from Einstein. Is there a problem that I am unaware of? I have installed the latest BOINC software and followed the suggested changes in this thread, but still nothing. Anyone have any idea whats going on?
RE: Is there a problem that

Yes, but it's probably a problem of your own making. It is likely that your computer is not able to complete tasks reliably within the deadline. BOINC is probably not allowing you to get new work because it has noticed this. The solution is to allow BOINC to be active per day for a bit more time than it currently is. The problem could be exacerbated by either an overly long estimate of the time it takes to crunch a result, or by a too small resource share for the E@H project.
When you last had work do you recall how long the estimated crunch time for E@H tasks was? Can you give an average of the time per day that your computer is actually on and crunching? Also, can you tell us the resource shares you have allocated to the two projects you are running?
This would only matter if you were getting exactly the same messages about insufficient disk space. Do you get the same messages? If you use the "Update" function in BOINC Manager to try to force more work, what are the actual messages that you get?
Cheers,

i haven't been able to get any new work either.
estimated crunch time for e@h is 18-22 hours/task. usually,i let it run 24/7. i hit the update button, and i get these messages:
1/16/2008 3:20:04 PM|Einstein@Home|Sending scheduler request: Requested by user. Requesting 0 seconds of work, reporting 0 completed tasks
1/16/2008 3:20:09 PM|Einstein@Home|Scheduler request succeeded: got 0 new tasks
i get the same messages when i hit the reset button.
i have a 150g hard drive, with 65g of free space. I've got the preferences set to use 5 gigs of disc space, memory usage is at 50% when in use, 90% when idle. actual disc usage is 40-75 megs for e@h, and about 5 megs for seti. even though i have it set to switch between e@h and seti every 60 min, usually both are running 1 task at the same time.
any ideas?
RE: i haven't been able to

Your situation is probably different again and is almost certainly due to a debt situation. You seem to have two projects, Seti & E@H and I'm assuming they each are supposed to have equal shares of the available resources. At the moment your RAC for EAH is about double that for Seti which suggests that E@H has probably enjoyed more than its fair share at the expense of Seti recently. This was probably caused by lack of work from Seti.
If you are now getting work again from Seti, BOINC will be favouring that project until the debt is repaid. As soon as everything is back to normal and Seti has caught up, BOINC will allow new E@H work to be downloaded. That will occur at BOINC's discretion and you shouldn't try to force the issue.
If you are wanting to know more, you can always browse the client_state.xml file in your BOINC folder with a text viewer like notepad and check out the values for LTD (long_term_debt) for each project. A positive value means that a project is owed that amount of seconds of CPU time. Be careful not to make any changes to the information you are viewing.
One final point - the reset button (ie resetting the project) will not reset your debts or force new work when BOINC has determined that you don't need new work at the moment. It does however cause any work in progress to be thrown away and is therefore potentially dangerous. It will force the download of fresh executables and config files and fresh data if there is no debt issue. You should use the update function rather than reset if you just want to force BOINC to talk to the project. The response will usually tell you why no new work is being sent (eg insufficient disk space, etc). If there is no particular reason given, it's pretty safe to assume debt.
