[hobbit] Message to long

[Colin Spargo]

Not as likely but still possible. I think the default limit is 25% of 
physmem, so it depends. If you have leftover segments or a small amount of 
physical memory then this may be the cause:

The error message that you got in the log definitely points to this:

"2006-08-07 16:23:54 Could not get shm of size 1048576: Invalid argument"

"Invalid argument" means:

"     EINVAL          The size argument is less than  the  system-
                     imposed  minimum or greater than the system-
                     imposed maximum. See NOTES.

                     A shared memory identifier  exists  for  key
                     but  the size of the segment associated with
                     it is less than size and size is  not  equal
                     to 0.

MAXMSG_CLIENT seems to need to allocate a shared memory segment of equal 
size. If your kernel shared memory settings are set too low (eg. if you 
are running defaults on solaris) then you may not be able to allocate the 
segment. If that happens, things like you just described seem to happen... 
  

you could possibly have dangling segments left over that were not cleaned 
up when you restarted hobbit, or possibly another app.

Try checking what is allocated with "ipcs -a", and increasing the 
parameter "shmmax".
