Cloud Build slowing down

Hi,

My builds are usually quite quick (the project is quite small and finished builds are around 170Mb) but over the last few days they have slowed down a lot, which is compounded by a large number of restarted & failed builds.

This came to a head yesterday when a build failed with a lot of the following output. The subsequent set of builds (Windows 64, 32, and Mac) took over two hours to build (the windows 32 bit took 6 hours!) There seems to be a long delay between a build failing and the next build starting - certainly the web interface isn't updating to show that the build is underway for hours.

Code (csharp):

1. Checking out files: 41% (1094/2606)
2. Checking out files: 42% (1095/2606)
3. Checking out files: 42% (1096/2606)
4. Checking out files: 42% (1098/2606)
5. Checking out files: 42% (1100/2606)
6. error: unable to create file Assets/Resources/Music/Binaries_Ingame_Music_09_Intensity2.wav.meta (No space left on device)
7. 16: error: unable to create file Assets/Resources/Music/Binaries_Ingame_Music_09_Intensity3.wav (No space left on device)
8. 17: error: unable to create file Assets/Resources/Music/Binaries_Ingame_Music_09_Intensity3.wav.meta (No space left on device)
9. 18: error: unable to create file Assets/Resources/Music/Binaries_Ingame_Music_09_Intensity4.wav (No space left on device)
10. 19: Checking out files: 42% (1104/2606)

 

This is what I'm currently seeing - the last build finished 15 minutes ago but neither of the queued builds have kicked off and there's no indication of why or what the system is currently doing

Ok, no idea what's going on now - an hour later and build 220 (Win 64) has completely removed itself from my pending build queue without any kind of warning or feedback.

We are getting a similar problem here, builds used to take around an hour.. Now they are taking on average around 6-7 hours..

When looking at the log it seems to be the get from Perforce that is taking the time.. But I can't tell whats wrong since when I check remote access to our perforce server I don't see delays anywhere close to that..

Any idea what could be causing this or how I can better see whats going wrong??
