Summary | 0007870: GC on save image or manual GC crashes image | |||||||||||
Description |
I have a fairly large image (~ 2800 Mb) and suddenly I cannot save the image anymore. If I manually run garbage collection, it seems to trigger the same, markAndTrace, function causing a SIGSEGV. I cannot reproduce with a clean image, unfortunately. See attached crash.dmp. |

I fear you may have hit a limit within the 32-bit VM. I cannot offer specific advice, but if you are able to ask on either vm-dev or squeak-dev lists, someone may be able to help. Based on past experience with other VMs, it may sometimes be possible to work around the condition by opening your image with a different VM (maybe the stack version for example), or by running it on a different platform (Linux or Windows). I do not know if that would help in this case but it may be worth a try. |

But this is a 64 bit VM: /Applications/Squeak.app/Contents/MacOS/Squeak: Mach-O 64-bit executable x86_64 I have been using squeak.cog.spur_macos64x64_<date>.dmg distributions since last summer. (Together with the 64 bit images). I have since rebuilt the image and loaded everything from Monticello. But, it is a good advise to use stack vm - I'll try that. |

Tim, if you are still having this problem, can you please open an issue on the opensmalltalk-vm issue tracker list at https://github.com/OpenSmalltalk/opensmalltalk-vm/issues [^] (and/or raise a question on the vm-dev list)? Other people on the vm-dev list may be able to offer advice, and if it is a VM bug it can be addressed on the github issue tracker. Thanks |
