[Lustre-discuss] failed to start lustre: problem with port 988

[neutron]

hi all,

 I m using  Lustre 2.6.18-53.1.13.el5_lustre.1.6.4.3smp.    I sometime
ran into a problem when starting lustre FS.   For example, I  usually
failed to start an OSS with some error messages appear in
/var/log/messages, like:

------------------------

It seems that Lustre modules need port 988 but the port is already
used by others.  But at that time "netstat -nap"  shows no proc is
using that port.
Is Lustre statically bound to the port 988?  Or is there anywhere I
can change the configuration so that Lustre doesn't rely on a
statically fixed port?   Thanks.
