Hola, I am trying to isolate the memory leak I suspect in a mailman installation ? I found: http://blogs.sun.com/sanjeevb/date/200506 It gives an error: god at irt-smtp-02:~ 9:21am 65 # ./memleak.d 10312 dtrace: failed to compile script ./memleak.d: line 3: probe description pid10312:libc.so.1:malloc:entry does not match any probes I am on SunOS 5.10 Generic_127112-07 i86pc i386 i86pc Are

Hi syslinux developers, As the title questions. Would like to know the status about 4k sector size support. I use the latest code build and use these library. Then try to boot on efi from my 4k sector size virtual devices. It always hangs on bootloader. I try to use the same bootloader and library on 512 sector size virtual devices and it works normal. Check the previous mail list...

...eally thorny issue where binaries build with clang and linked with lld was just "Killed" when started on a specific armv7 device we ship on. After quite a bit of head scratching it turns out that the kernel on this device ships with a 32k default page size (getconf PAGESIZE) and lld uses 4k default page size. We fixed this by passing -zmax-page-size=0x10000 to lld. The default page size in GNU ld for arm is 64k so binaries linked with ld just worked on this device. I put the question in the discord lld channel and after a bit back and forth I think it's better to discuss it her...

So, what is the story about 4KB disk sectors? Should such disks be avoided with ZFS? Or, no problem? Or, need to modify some config file before usage? -- This message posted from opensolaris.org

I installed C7 along with MATE desktop... My monitor is a 4K unit but when I goto the System -> preferences -> hardware -> Displays there is selection for the 4K display. It stops at 1920x1080. The var log x file shows the 4K resolutions in the file so that is good. How do I get the selections for 4K to show up? Thanks, Jerry

...problem also exists on Solaris hence this email.] Summary: on ZFS, overhead for reading a hole seems far worse than actual reading from a disk. Small buffers are used to make this overhead more visible. I ran the following script on both ZFS and UF2 filesystems. [Note that on FreeBSD cat uses a 4k buffer and md5 uses a 1k buffer. On Solaris you can replace them with dd with respective buffer sizes for this test and you should see similar results.] $ dd </dev/zero bs=1m count=10240 >SPACY# 10G zero bytes allocated $ truncate -s 10G HOLEY # no space allocated $ time dd <SPACY &...

Hi ZFS Discuss, I have a 8x 1TB RAIDZ running on Samsung 1TB 5400rpm drives with 512b sectors. I will be replacing all of these with 8x Western Digital 2TB drives with support for 4K sectors. The replacement plan will be to swap out each of the 8 drives until all are replaced and the new size (~16TB) is available with a `zfs scrub`. My question is, how do I do this and also factor in the new 4k sector size? or should I find a 2TB drive that still uses 512b sectors? Thanks

One of the issues of current balloon is the 4k page size assumption. For example if you free a huge page you have to split it up and pass 4k chunks to host. Quite often host can't free these 4k chunks at all (e.g. when it's using huge tlb fs). It's even sillier for architectures with base page size >4k. So as long as we are chan...

Hello all, I get the following error when I stuff my seesion with more than 4k of data. CGI::Session::CookieStore::CookieOverflow My problem is that I obviously need a fatter session. How do other users by-pass the 4k restriction on session variables? Regards, John --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed...

Guys, Is there support for display port 1.2 with the nouveau driver and GTX 970? I have a dell 4K monitor and to run it in 4K mode at 60Hz I need to configure the monitor to run version 1.2 of the display port protocol. the nouveau driver works well with display port 1.1 but I only get a 30Hz refresh rate at 4K resolution. thanks.

...that require scrambling by booting with nouveau.hdmimhz=340.

...t; If not, it's probably something else. But this seems like a likely candidate. There is nothing in dmesg. Maybe nouveau needs a module parameter for debug logging? I'm going to try a different cable anyways. Is there something in /proc to check if "scrambling" is on?

...make it impractical to copy with a file-oriented approach. The current filesystem is ext3 with one partition that uses the entire disk capacity (no lvm). It works as is, but... I'd like to use a laptop size drive for the swapped member and the only ones available that match the size have 4k sectors. I have swappable, trayless SATA bays available for both drive sizes. The problem is that with the current partition layout, the drive with 4k sectors takes more than a day to re-sync even though on read access the speed is a match for the full sized drives that sync in a few hours....
