Thanks for the report, could you add some notes about what HW/OS this happened on and what steps might reproduce it. Was there more to the stack trace, perhaps other go routine stacks? Even if you can't reproduce it easily the information is important to us. |
|
linux/amd64 ubuntu 14.04 process ran for about 2-3 days, there was no evidence of memory issues when it triggered, nothing unusual was occuring in the logs or elsewhere. i have no other stack traces, sorry |
|
That's unfortunate, does this program normally run 24x7 so that when we fix the elusive "last known bug" we can have some assurance that this one is also fixed? Say by letting the application run for a week. In any case thanks and keep sending us any bugs you sight. |

Yes it runs for upwards of a week between updates. |

It frequently occurs with gorename. runtime:greyobject: checkmarks finds unexpected unmarked object obj=0x20ad94238, mbits->bits=0x1 *mbits->bitp=0x9b runtime stack: goroutine 3 [garbage collection]: goroutine 1 [runnable]: goroutine 2 [force gc (idle)]: goroutine 4 [GC sweep wait]: goroutine 5 [finalizer wait]: |

I've not seen the problem since I last reported it. I've used this go go version devel +edadffa Fri Feb 20 18:31:25 2015 +0000 linux/amd64 On 8 March 2015 at 13:34, Dylan Visher [email protected] wrote:
