Title: Ansible & Windows - Timeouts, Stack Overflows, Out of Memory Date: 2014-08-30 Tags: devops, ci, continuous-delivery, ansible, windows, errors
I have been using Ansible & Windows to prepare my Jenkins clients. I
have used both the
win_msi package from the mainline, as well as
win_package module which offers a lot of enhancements.
While testing out the base
win_msi, I kept getting Out of Memory
exceptions, Stack Overflows, HTTP 500s & timeouts. I found out about
Trond’s enhancements to the
win_msi module, as well as the addition of
win_package module, and so I tried them as well, with the same
results. Sometimes, everything went fine; sometimes it did not.
Seeking help, first Trond teased me about it not being 1990 and told me to add more memory to the machines! :-D That was awesome, and made me double-check that these weren’t severely crippled, and they weren’t.
What I was encountering turns out to be a bug in Windows gasp where it limits the amount of memory given to WinRM to 150MB, despite whatever the environment reports is allocated. (Mine was on Server 2012, and was defaulted to 1GB)
See this thread for more information; it covers a few topics but about half-way down you’ll see them discuss it. If that is the error you’re encountering, it’s corrected by KB 2842230, which at the time of this writing, is still undergoing testing and is not in the Windows Update catalog yet; you have to manually download it and apply it.
