Try increasing the Maximum Disk Usage setting in your profile. I updated mine from 10Gb to 20Gb and the errors seem to have gone away.

When only some of the wingmen are getting it the issue might be they have their client settings too low and that's causing the error instead of the project limit.

?

Key elements, memory [RAM and VM] and allowed / used disk space is printed at start of event/message log and anytime the prefs are updated, these get reprinted. Else the global_prefs and global_prefs_override [if using local prefs], contain all settings in text form... easy to copy/paste, but find rare need for these... the log suffices.

Whilst, in the example, if 4 CEP2 are running and using e.g. 4GB out of 10GB set, and a new CEP2 task is requested, the server client interaction checks if 2GB [BOINC allowed] disk space is free as well sufficient memory, i.e. real time check that 6GB can be used by BOINC atm the time of receipt. Can only repeat, the topiced issue is logged when the -individual- model has grown over it's limit [2GB]. I just looked on another client and this shows for all 4 running CEP2

<rsc_disk_bound>2147483648.000000</rsc_disk_bound>

The said 2GB free that's checked prior to assigning a task, which is when the model wishes to go above, it craps out, and -that- is more often, but still relative rarely used [obese molecules maybe]. Not incurred on 35 jobs since the start of this thread... < 3% [and my disk setting has been 22GB for a very long time... all space of the exclusive BOINC G: partition, and yet I got these errors]

edit: Maybe in a future, far far away, the web device profile settings could be made to easily copy paste... those are the ones that have a preferred use [and to which techs have access]. Right now, copy/paste and you get this... no values that are shown on screen:

Disk Usage
Use no more than: 		Gigabytes of disk space
Leave at least: 		Gigabytes of disk space free
Use no more than: 		% of total disk space
Write to disk at most every: 		seconds

Sunday Oct.27 and it's wintertime again, a good discussion in Europe ongoing to make DST permanent [except for the Spanish... they want permanent wintertime... better suiting their lifestyle] Permanent DST -does- save lives too [commuters killed in evening traffic... when we're tired of the hard days night]. Have a good day, all.

Thanks armstrdj

Still getting errors with 20Gb Max Disk Usage in my profile. Reverted back to 10Gb.
Problem seems to only be happening on my Linux boxes. Not getting any disk space errors on my Windows boxes.
Most wingmen are getting the same error. But some wingmen are able to complete the failing units.

We have increased the limit of temporary disk space that CEP2 can use from 2GB to 2.5GB. If you continue to have issues please let us know.
Thanks,
