From edc8ac624641c23c0c081c33dac6ed068c39ca72 Mon Sep 17 00:00:00 2001 From: Felix Fietkau <nbd@openwrt.org> Date: Mon, 18 Nov 2013 13:32:06 +0000 Subject: [PATCH] uClibc: Deactivate oversized thread stack cache A small system like the common home router doesn't have 40 MiB per process for a dirty stack cache. This can easily lead to an overbooking OOM problem and caused a lot of hangs+reboots on 32 MiB systems running nodogsplash. Not using a stack cache can increase the time to spawn new threads. This is hopefully no problem for system not running a lot of parallel computations.
