Back in May a few messages went around about problems with the Meiko
svcs daemon hanging up for no apparent reason.  I've recently acquired
an M-10 unit (I haven't actually seen the thing since I'm running remotely)
and am running CStools on a SparcStation using SUNOS 4.0.3c.  I've now
got the same problems!  Programs which run okay most of the time will
suddenly hang for no reason.  Once I've breaked from the program, the
svcs daemon has frozen and must be restarted before using mrun again.
 
Since this problem has obviously been around for months, has anyone
found or been given a solution?
 
While I'm on the subject of Meiko, I've come to realise (since I can't
find it mentioned the documention) that byte orders need reversing when
sending data (using csn_rx and csn_tx) between a process on the host (Sun)
and a process on a transputer (by the way, I'm using FORTRAN but I've
tried C and it's the same).  I get round it by swapping the bytes before
sending.  Has anyone found an easy way round this, or is there something
I've missed in the documentation?
 
Thanks

I have never had this problem on our unit, but if I did I would harass
Meiko until they fixed it.  I would recommend that you do so, too.

Yes, the byte order is different.  Meiko supports the xdr functions (as does
Sun) which is the (supposedly) portable way of dealing with the issue.  There
is no easy way around it.
