[Moosefs-users] TCP: time wait bucket table overflow (CT0)

[Giovanni T. <gt...@li...>]

Hi,

I'm getting a lot of errors on both chunkserver dmesg:

TCP: time wait bucket table overflow (CT0)
TCP: time wait bucket table overflow (CT0)
TCP: time wait bucket table overflow (CT0)
TCP: time wait bucket table overflow (CT0)

Googling around, seems a problem of exhaustion of available sockets and
a good workaround seems to enable tcp_tw_recycle

echo 1 > /proc/sys/net/ipv4/tcp_tw_recycle

TCP_WAIT connection dropped from 4859 sockets to near 0 in the next few
minutes.

Anyone got this issue with latest MooseFS under Debian Squeeze?

Thanks.
