We are not *that* intimate with the kernel.

I've just discovered that the hosting company has a mechanism for killing processes that it believes are consuming too much memory. When git does it's mmap's it looks like it is using over 512MB of memory which causes it to get zapped. At least I think this is what is happening. -- Jon Smirl jonsmirl@gmail.com ``` ## Nicolas Pitre, 2007-11-09 19:27 Subject: Re: git push failing, unpacker error Message-ID: URL: https://gitlist.dev/e/alpine.LFD.0.9999.0711091416070.21255%40xanadu.home In-Reply-To: <9e4733910711091009q2c6409fdj75cf8051d073c9c5@mail.gmail.com> ``` On Fri, 9 Nov 2007, Jon Smirl wrote: > On 11/9/07, Junio C Hamano wrote: > > "Jon Smirl" writes: > > > > > On 11/9/07, Jon Smirl wrote: > > >> I updated both sides to current git and it still fails.

You might be interested by the following config variables: core.packedGitWindowSize core.packedGitLimit core.deltaBaseCacheLimit pack.windowMemory pack.deltaCacheSize Certainly one or more of them could be tweaked in the remote repo to solve your problem. But since your problem happens on push then you should look at the core variables first. Nicolas ```
