It's definitely a memory leak issue and little to do with the zergs and impulse spam.

Having crashed multiple times tonight whenever memory usage hit 90% of my 8GBs, I asked my guildies to check their whenever they crashed and everyone confirmed their memory usage peaked at extremely high numbers before the crash.

We did find that disabling add-ons slowed the crash rate slightly, so whether it's because they need to be updated or not to stabilize the game I do not know.

zergballs have been causing server crashes for weeks, long before this patch.

Most definitely, but nowhere near the same frequency as it's been since the new patch.

Whether it's an actual memory leak or just tied into the add-ons is something that I haven't tested and, out of laziness, probably won't.
