Apache 2.4.7 on Ubuntu 14.0.4 inside a Docker container on OSX randomly gives the following 500 error while requesting random static files during a page load: Error reading /var/www/.htaccess on line 1: Bad file descriptor This only started happening after updating to Docker 1.11.1-beta13

2GB is a ton of memory! What kind of mac are you running that you can allocate TWELVE GIGABYTES to Docker?

You’re right, 2GB is a ton of memory for Docker. We’ve got about a dozen containers we’re spinning up and pretty large code base. I increased it to 8GB and noticed better performance. Today I’m putting it back down to 4GB and we’ll see if there’s any noticeable difference.

I’m getting the same errors. On a long make, not consistent, it seems to happen after the compilation goes for a while. I’ve got 4GB allocated to docker, so will try more.

Also check permissions. Is this related to the UID/GID ticket? If it’s not readable you’d get bad file descriptor.

Sorry what’s the UID/GID ticket, is there a github reference. It is strange because it is doing lib tool or gcc against a long list of files and then one fails randomly.

Thanks for the points @stupschwartz , that does not look like the problem. All the GID and UID are correct (this is for a developer image so we match the outside and inside GID/UID in the Dockerfile). It sure looks like the file system is not keeping up. the offending command from the make runs fine…

Timing bug would explain a lot of the other issues I’m seeing. Including this other ticket I put in ERROR: Bad Response from Docker Engine

Is this where we notify folks. Is there a github issue we should open like with the core docker development?

Hi Richard, We are working on a fix and will push out an update soon. Thanks for participating in the Docker for Mac Beta! Best regards, David Sheets
