Hi folks, I've been getting a few work unit errors from one of my machines and was hoping someone might be able to explain what they mean.
----------------------------------------The old beast is a P4 1.7GHz cpu, 768Mb ram (DDR266) running as a headless system. It's running BOINC 5.4.9 on Ubuntu 5.1 linux. No other applications are running. Anyway here's one of the messages from the units.: <core_client_version>5.4.9</core_client_version> <message> process exited with code 131 (0x83) </message> <stderr_txt> terminate called after throwing an instance of 'std::bad_alloc' what(): St9bad_alloc SIGABRT: abort calledStack trace (25 frames): [0x806840c] [0x8074a7c] [0xffffe420] [0x80d9354] [0x80c02db] [0x80c7321] [0x80c7356] [0x80be4a3] [0x80be5dc] [0x80a3b1a] [0x80a4147] [0x80a43f4] [0x806437c] [0x80648fc] [0x8064a4a] [0x8049444] [0x8060259] [0x804934c] [0x804b91b] [0x805ae7a] [0x805b061] [0x805dc1d] [0x80486de] [0x80d2294] [0x8048111] Exiting... </stderr_txt> Can anybody tell me what this means? The majority on units from this system validate fine, but there have been two errors in the past 24 hours so I figured I should ask.  Currently being moderated under false pretences |

Hello Dark Angel,
----------------------------------------What status has been assigned to the other work units in the quorum? (Click on the work unit name on the Results Status page.) Lawrence Added: http://gcc.gnu.org/onlinedocs/libstdc++/lates...assstd_1_1bad__alloc.html Maybe you ran out of free memory. I suppose that a few HDC work units might be unusually large. Another possibility might be some bad RAM. [Edit 1 times, last edit by Former Member at Oct 4, 2006 12:25:14 AM] |

The status said "error" which I clicked on to get the info I posted above.
----------------------------------------Like I said, I have 768Mb in that machine and only BOINC running over the operating system. I even have screen-saver, printer and every other service I can find in there disabled or removed to reduce memory/cpu overhead. I've run memtest through it recently and it came up ok. I suppose I ould run the cache down and reset the project as a precautionary measure. Currently being moderated under false pretences |

Hello Dark Angel,
If you click on the Work Unit Name, not the Status, you can see if anybody else ran into the same problem, or if only your computer had a problem with that work unit. Lawrence |

I hadn't thought of that, thanks. I've just had two more do the same thing, so I'm resetting the project. I had a day's work cached, so I'm not happy about killing that but I'd rather they get done right than corrupted by something stupid.
----------------------------------------I'll have a look at them as well and see if it's just me. Currently being moderated under false pretences |

Hi Dark Angel,
----------------------------------------Did a search here: http://clusty.com/search?query=terminate+call...p;sourceid=Mozilla-search The returning theme is "program low on memory". I'm actually not surprised as on my windows system i've seen registered peak RAM usage by HDC of 725mb (Taskmanager has option to add this column). With the OS running and BOINC needs itself, i'm not surprised that 768 is a squeeze. WCG might have to lower the program needs or up the spec requirement. ciao

Is it specific to RAM or does that include virtual memory?

no, the measurement is RAM only unfortunately. Swapfile is a different parm but has no peak recording track for a specific app. At the moment got one which topped at 702mb RAM so far and only 25 minutes into the crunch.

Thanks,
---------------------------------------- I've updated my kernel and have just now launched another run of memtest to see what comes up. I'll be very disappointed if it turns out my hardware is faulty but I'd rather not be returning dud units whatever the cause. Currently being moderated under false pretences |
