It did not seem to have any issues until this run a week ago @ r203162 https://build.webkit.org/builders/Apple%20Yosemite%20%28Leaks%29/builds/6807

Monitoring it over the course of a test run, the OS volume usage was at least 93% before the test timed out. Not sure if that is related. https://build.webkit.org/builders/Apple%20Yosemite%20%28Leaks%29/builds/6930/steps/layout-test/logs/stdio

The bot shows a "Your system has run out of application memory" dialog.

Looks like the crazy memory use is in Python process.

The stdio log is huge, ~50 MB - but it's been like that for a month at least.

There is a large leak under WebCore::CGImageEncodeToData. But it's not a regression, it's been present in the oldest build that is still available - r199810. https://build.webkit.org/LeaksViewer/?url=%2Fresults%2FApple%20Yosemite%20%28Leaks%29%2Fr203549%20%286936%29%2F

The bots disk is filling up with swapfiles. The Python process is using upwards of 25GB of memory.
