rsync triggers oomkiller

I've not encountered oomkiller being triggered when the server has free memory and hasn't swapped to disk yet. After the fact, it will probably be almost impossible to figure out the list of files that rsync was storing in memory. This makes me wonder if there's an option to have rsync log the list of files (to be s...

system unresponsive
...od servers) but I tracked it down to a problem in the XFS driver, as it never occurred on the systems with EXT4 filesystems. The XFS driver would hang, preventing writes to the filesystem. I could identify exactly when that happened as all system logging would suddenly stop at the same second. Then OOMKiller would come in and start killing off processes but that wouldn't be in the logs on disk because the file system couldn't write. I rolled the servers back to a 5xx series kernel and the issue didn't resurface. I recently let them boot the newer 9xx series kernels and I'm hoping the...

MediaTemple Image upload
Hi All, I''m hosting with MediaTemple who are currently using 0.3.3 of mongrel on their GridServer. My rails app has an image upload facility whereby if you upload a large image (e.g. 5Mb) mongrel crashes. I''ve requested an upgrade to the latest version of mongrel but don''t believe that''s going to happen too soon. I''m not getting too much

Why does my DomU keep going mad?
Hi All, I''ve got a DomU that sometimes goes mad. I can''t ssh or usually even console to it. The time I did manage to console I got a load of dumps about being out of memory and swap, but couldn''t run any commands to find out which process had gone mad :( From Dom0 I can see the DomU at 100% CPU and can only stop it with a destroy. What can I do/check to find

Fwd: Re: Swap: create or not?
...sed as buffers/page cache and effectively reduce IO load on shared storage. Second very important usage: when user processes starts to eat memory, it is some lag until we add more memory. Of couse every VM have some free memory, but in case it was not enough - swap will save guest VM from been OOMkilled. So I strongly supports for domU swap. -------- Original Message -------- Subject: Re: [Xen-users] Swap: create or not?

Spawn mongrel on demand
Hello Zed ! Do you knows or plan a way to spawn mongrel processes on demand ? I''m studying options to build an affordable but solid shared hosting solution. You wrote something very promising in your "NEXT STEPS", A combination of the ''"mostly C version'' and the mongrel_cluster replacement would be an elegant method to save much RAM on servers (until

Xen HVM and tap:aio
...t lists.xensource.com Hello, I'm not able to use tap:aio disk definitions with my HVM domU's. Is this supposed to work on this version of Xen, or am I doing something wrong? I've tried everything I can think of. file: works, but not tap:aio: , and I understand that file: will cause OOMkiller if using NFS mounts and is deprecated. Likewise, tap:aio: for cdrom does not allow me to boot off of cdrom; file: does work fine. Furthermore, any time I use tap:aio, the bochs bios of the hvm domU shows the hard disk size as 0 MBytes. Any disk definition that I use that has tap:aio: gives th...

It doesn''t bypass the buffer cache (so all bets are off for data integrity) and can end up consuming all of dom0 memory with dirty buffers -- just create a few loop devices and do a few parallel dd''s to them and watch the oomkiller go on the rampage. It''s even worse if the filesystem the file lives on is slow e.g. NFS. > AW> Julian and I have talked about extending the tap driver to combine > AW> it with blkback and allow block address translation without access > AW> to request contents. >...

Xen Roadmap proposal
...g updates to the console frontend driver, xenconsoled, and the tools. When using `xm mem-set'' commands to control the amount of memory in a guest its currently quite easy to set the target too low and create a `memory crunch'' that causes a linux guest kernel to run the infamous `oomkiller'' and hence render the system unstable. It would be far better if the interaction between the balloon driver and linux''s memory manager was more forgiving, hence causing the balloon driver to `back off'', or ask for more memory back from xen to alleviate the pressure (u...
