[Bug 16916] CoH Updater causes Segmentation Fault

--- Comment #8 from Michael Earl   2009-06-21 22:19:55 ---
On suggestion of a message on CoH page here, I tried

#echo 4096 131072 3612672 > /proc/sys/net/ipv4/tcp_wmem
> From my default setting of "4096    16384    3612672", and this seems to have

resolved the issue!  As far as I can tell from 5 minutes web search, this
increases the default process maximum for TCP buffers from 16K to 128K. 
(Possibly this explains the strange "getsockopts" behavior?).  Increasing the
value only to 64K resulted in crash later in the process.

FWIW, I also understand that adding

net.ipv4.tcp_wmem="4096 131072 3612672"

To /etc/sysctl.conf would have the same effect across reboots, but have not
tested that yet.
