[comp.sys.masscomp] file system problems

jes@mailrus.cc.umich.edu (Judith Stinehour) (04/26/89)

We have a masscomp 6700 with 4 cpu's and 24 meg of memory, and have been
plagued with problems ever since its purchase.  Specifically, we have been
having a problem with the following error message:

fpalloc: System wide open file limit exceeded

This pops up on the console.  Any successive job by another user gets
this on his login window:

/etc/mtab file table overflow

Incidently, we are running Xwindows.

This problem seems to crop up when we run compression routines. (we
are doing some testing of a variety of compression techniques) and we
consequently have a large amount of pipes and processes running.  

Masscomp suggested raising the inode and nfile variables in the
configuration file from what we had a couple of days ago (300) to 
what we have now (400).

But it didn't work.

If anyone else has had problems with their 6700 we would like to
hear about it. Our load balancing, for example, doesn't seem to work as 
advertised.  sun workstations with a single 68020 run faster then the 
masscomp with it's 4 68030's.

In addition, the tape drive takes about 1 and 1/2 hours to load up a full
6250 1/2 inch tar format tape.  Is this correct?  It seems awefully slow
to me.
