Looks like the number of threads being created is using up stack memory.Try reducing the amount of stack memory allocated to each thread on creation. -Xss depending on what JVM you are using try setting it to minimum.On 22 Jul 2017 17:46, "Mikhail Krestyaninov" <mikhail.kr...@gmail.com > wrote:Hello....I have a very big GWT project which recently has become a bit more bigger.

During the compilation process I can see (in Activity Monitor) that the amount of threads for DevMode process raises up to 2K and then the error occurs. As far as I can see, the default limit of threads per process on MacOS ("sysctl kern.num_taskthreads") is 2048 which means that I hit it. Changing Xmx limit (obviously) doesn't solve the problem.I tried to decrease the amount of local workers, but faced the following error:
