armstrdj, with the latest Betas that I am receiving, they seem to run okay - they end up valids but, even with having the earliest deadline of all the tasks on a machine, are not starting immediately after downloaded. I had four last night that eventually ran and validated fine. I just suspended all tasks on one machine except for the Beta and it did start. It appears to be running fine so far. Here's the event log covering the time I did the suspended and resuming to start it:

<event log emailed to support id>

EDIT: Okay, now it looks like it is restarting again like before. Sent more of the event log in to the support id with the debug info. The percent complete and elapsed/cpu time appear to reset separately. The is on Ubuntu so I checked the console once it was restarting and saw that it was saying something about memory errors - I think "unable to allocate" - like it kept getting the memory it thought it needed each time it restarted and eventually ran out. All the others are still waiting to run and I'm not going to force them to start to see what happens. Can't imagine why using suspend/resume to force a WU to start would cause a problem like this? I rebooted the machine and the beta is running again.

I have to agree with this. Running a Redhat 6.x derivative on an old Atom with 4 threads and 2G memory (maximum board supports) and boinc 7.2.33-3.git1994cc8.el6.i686.
It's intermittently switching between the following tasks depending upon memory pressure from other applications...
2x Beta 2x Zika
3x Beta 1x Zika
4x Beta 0x Zika
I've upped the memory available to boinc in global_prefs_override.xml, both idle and busy, which helped a little..

Edit: Should also have mentioned that # pages in /sec and # pages out /sec as recorded by sysstat has sky rocked once the number of Betas received and trying to run at once went over qty 2... Swapping is also way up...

Update: Noticed a new mode 3x Beta 0x Zika ie only 3 of 4 CPUs active - seems like the extra memory available allows a minimum of 3x Beta so far...
Monitoring now to see the changes on a graph... See http://www.sraellis.tk/frame-14-wcg_tasks_saved.html

Using a combination of my own custom scripts, scripts taken from these forums and mrtg to graph WCG monitoring, with custom scripts, sysstat, lm_sensors, ntpq, mrtg etc for system monitoring... mrtg is pretty old - but this old dog hasn't time at the moment to learn new tricks...

Just spotted a wingman with an Invalid result, and a Result Log line saying "Could not determine result number" (but otherwise normal-looking, although with a checkpoint restart). This is now the 3rd such example, all of them using client version 6.10.58.

Start of Result Log:

Edit: updated status after my copy finished and validated.

Found WU BETA_beta26_00000060_1262_0 with an Elapsed time 2 days and did not seem to be moving. It was but very slowly. I suspended the other jobs running to give the Beta more resources which did not help.
Next I suspended and resumed the Beta WU.
