What is the max number of mutexs that can be created?

[Eric Norum]

It depends -- in most cases you are using a 32-bit object ID, in which case you have up to 65536 instances of each object type.     
For very small systems you can use a 16-bit object ID in which case you can have only 256 instances of each object type.

See http://www.rtems.org/onlinedocs/releases/rtemsdocs-4.10.0/share/rtems/html/c_user/c_user00023.html for details.

You can also configure the number of each type of object to be expandable at runtime.
