<br>
The error is coming from libqb - which is what manages the local IPC <br>
connections between local clients and the server.<br>
<br>
I'm the libqb maintainer but I've never seen that error before! Is there <br>
anything unusual about the setup on this node? Like filesystems on NFS <br>
or some other networked filesystem?<br>
<br>
Other basic things to check are that /dev/shm is not full. Yes, normally <br>
you'd get ENOSPC in that case but it's always worth checking because odd <br>
things can happen when filesystems get full.<br>
<br>
It might be helpful strace the client and server processes when the <br>
error occurs (if that's possible). I'm not 100% sure which operation is <br>
failing with EREMOTEIO - though I can't find many useful references to <br>
that error in the kernel which is also slightly weird.<br></blockquote><div><br></div><div>EREMOTEIO is being used for the obvious purpose in pacemaker.</div><div><br></div><div>Klaus</div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
