I''m running into a situation where I can''t unmount a mounted snapshot. It shows "busy" even though neither lsof nor fuser show any open files. Umount -f doesn''t work although umount -l does. Is there anything else I can do to debug this scenario or to clear the busy status myself? Or am I down to rebooting each time? This is on stock ubuntu-10.04, x86.

Boy am I a dummy. I want to simply dump out unfreed allocations when I terminate the script. What''s the secret sauce? #!/usr/sbin/dtrace -s pid$1::MyAlloc:return { bufs[arg1] = walltimestamp; } pid$1::MyFree:entry /bufs[arg0]/ { bufs[arg0] = 0; } This message posted from opensolaris.org

From: José Fonseca <jfonseca at vmware.com> When the hash function uses object pointers all free entries eventually become tombstones as they are used at least once, regardless of the size. DenseMap cannot function with zero empty keys, so it double size to get get ridof the tombstones. However DenseMap never shrinks automatically unless it is cleared, so the net result is that certain

Does LLVM try and make sure that all memory is freed before compiler exit? For example, It seems like the ARM constant pool code that I'm reading will leave a lot of un-deallocated memory. Maybe I'm missing something here. Reed

Jonathan Armani (armani@) advises moving it down. Same thing happens in do_readlink(): if it's unable to readlink(), the function returns without freeing msg. I've attached a patch. This runs on both openbsd -current & portab...

It can be very important if you're using llvm/clang as a library instead of a stand-alone process. If a compilation does not free all of its memory and is repeatedly invoked, this can lead to increasing memory usage. I'm not saying this is the cas...

...et some wiser guys determine if there is a duplicate. And maybe it would not even apply to nouveau. I have a crash, happening after a few days of use, that I reproduce all the time after few days. I have not able to determine what could be the cause, but it may be because of the cache that ends up unfreed and lacking of space. The symptoms vary, but it doesn't necessarily make my xorg crash. I am commiting now, with the nouveau "crash", with firefox. So that means it is not a complete crash. But I can't launch vlc nor a Konsole. There is my setup: lspci -vvv gives this graphic ca...

I''m a fan of ZFS since I''ve read about it last year. Now I''m on the way to build a home fileserver and I''m thinking to go with Opensolaris and eventually ZFS!! Apart from the other components, the main problem is to choose the motherboard. The offer is incredibly high and I''m lost. Minimum requisites should be: - working well with Open Solaris ;-) -
