uwsgi process died with "libgcc_s.so.1 must be installed for pthread_cancel to work"

Question

uWSGI runs on CentOS 5 with python2.6

Sometimes, the below errors show in uwsgi log:

libgcc_s.so.1 must be installed for pthread_cancel to work DAMN ! process 2474 died :( trying respawn ... Respawned uWSGI worker (new pid: 6328)

I searched on web, but I don't understand why this happens.

More info:

This error is generally because uwsgi configuration. Lets you "limit-as" becomes larger, or remove the restrictions. But I also strongly recommend that you use cgroup
