Is there anything unusual going on like a server down causing autofs to issue a number of mounts that are all waiting to time out? > Oct 20 00:38:52 kenny automount[2293]: unexpected pthreads error: 11 at > 65 in cache.c Mmm .. if this is a genuine autofs issue maybe I need to handle EAGAIN returns but that would mean blocking which probably isn't good and I'd rather not if we can avoid it. > > I am not sure if this is due to autofs changes or changes in some other > code that was merged.
