/me just wondering whether 2 errors of that kind in a row since I'm running the new linux kernel are related to it or not.
Anybody made similar experiences ? |

If you visit the Result Status page and click on the error link, then post the log, we could tell you something more. CEP2 does not like excessively busy systems, particularly on Linux.

Signal 11 and parent was killed, probably when job #10 was underway. are the signs of a too busy system, not specific to any Linux kernel. I've got BOINC set [on Ubuntu 11.10] to pause when the non-BOINC system load is greater than 35%. (also with "Leave Application in Memory when suspended). This stops BOINC for 10 second segments long as the system wants attention. Better to have CEP2 pause a few minutes, than crash out or revert to last checkpoint that can be hours computing time back.

I also have another anomaly. this one probably does not have anything to do with WCG or BOINC Just let me know if there could be any connection with this issue. A two year old I7 950 quad core with a mild overclock (3.9 GHz) that normally runs a CEP p2 in 9-11 hours, is now taking 38-45 hrs per work unit. It's got plenty of memory (24 Gb) and hdd (7200 sata II 1TB. My other Sandybridges are doing fine.

Good question. I was simply looking at the "to Completion" colume. When I went to the results page and check several of the Valids and Pendings, the time were in the normal or better than normal range of 6-9 hours. I'll put a clock on a unit and determint the actual clock time.
----------------------------------------I reset the project last night but the results were the same. Thanks for the help |

Well, the system isn't too busy, but booted from an external USB drive - therefore - yes - sometimes it might take longer than usual to access certain data segments.

I've got Ubuntu 12.04 on a USB 3.0 Sandisk stick and consistently saw HCMD2 and CEP2 fail. All other sciences did fine. BOINC was set with an enforced start delay [can be set in the cc_config.xml with the <start_delay>xxx</start_delay> options line, value in seconds]. Maybe try that as a possible mitigation.
