I received the above msgs in my msg log. I was wondering if the 'no fished file' may have happened because computation was suspended just prior to the error msg. I am running Mac OSX 10.5

I'm quite sure that the suspending was not the cause. In any case don't reset the project! A simple restart of BOINC should be enough, if needed at all.
If that message appears only sporadically (2-3 times a day), just ignore it. It often is caused by automatic adjusting of the system clock by time servers.
If it appears often (about every few minutes), you have to check the log file stderr.txt in the appropriate slots directory for the cause of the error, because after 100 retries, the Task will be aborted.

Each time this message appears, the work spent on the WU so far is abandoned/wasted, so this is something to worry about.
The problem might be a too small shared memory config under MacOS. This is more frequently seen on systems with more than two cores, but you never know, it might be worthwhile to try this fix, as quoted here.
Happy Crunching

RE: RE: Sun Dec 28

I'm running it on a new UniBody MacBookPro so it only has the two processors. But one additional detail I thought I'd mention. In the thread you pointed to, it mentioned BOINC not always doing a complete job of cleaning up the shared memory segments when it crashes or gets shut down. While I haven't noticed any crashes recently, I have been stopping and restarting BOINC between reboots to disable it when playing back video.(Boinc takes up to much CPU and lowers the frame rate). I stop instead of suspending so that in case I forget it will worst case be reactivated the next time I reboot
Also I do have 8 projects installed in my system, although one is suspended due to not currently having any work for my processor type. Although at the time of the failure I believe that only 3 had tasks in the local queue.
Also I only mentioned the "Suspending computation - user is active" msg because it happened (without a corresponding reactivation) 11 seconds prior to the task being completed and getting the error. I would thought work would have stopped and therefore would not have completed till things were started back up again. But maybe there is a lag between the "Suspending computation - user is active" msg and work actually stopping
RE: Also I only mentioned

If you have Leave applications in memory while suspended? in your preferences set to yes, then the aforementioned system-time reset will cause every task in memory to give the message (without losing work done), whether active or not.

In my case Leave applications in memory while suspended? is NOT checked. But here is the startup status info from my system.

RE: RE: RE: Also I only

With this statement by you too "Also I do have 8 projects installed in my system" you should DEFINITELY have the box checked. You are depending on your system drive to keep all that data while doing everything else too, not a good scenario. You also might try stopping crunching for some projects and try to focus on an elite few. With that many your pc must be switching from project to project constantly!
RE: With this statement by
)
That's only true for projects that don't do checkpointing.
?????????????
If you mean with 'constantly' every hour (default preferences), then you are right, but I don't see a problem with that.

RE: RE: You also might

Actually I was thinking of the LTD you must be accumulating because of the many projects and their individual deadlines all being different. But I guess as long as it is working for you, keep up the crunching!
RE: RE: RE: You also
)
While there are 8 projects installed, they are are not all active at the same time. One currently has nothing for the mac. Another comes in spurts, with new data to crunch at the start of each month. The climate one has a 12 month deadline. Other than the originally mentioned error things are running fine.
BTW the next work block from E@H seems to have run OK
RE: If it appears often

Is there anything that can be done then if it keeps happening? Here are the kinds of messages that keep showing up in the stderr.txt file when one of my WUs tries to run:

I've suspended this task and am hoping that I haven't lost several hours of work.
Thanks for any ideas! :-)
