Am I hitting the static route limits in my c3750?

I'm having a very odd issue with my c3750 where by I think I'm hitting the static route limits. If I add ANYMORE routes to the switch (in this case a block of 16 ips), it immediately stops taking traffic (we have HRSP configured) and all my secondary switches tied through it immediately fail over the redundant c3750 switch.

As soon as the route is removed, everything goes back to normal.

Here is some info that hopefully helps:

#sh version

Cisco IOS Software, C3750E Software (C3750E-UNIVERSALK9-M), Version 12.2(40)SE, RELEASE SOFTWARE (fc3)

cisco WS-C3750E-24TD (PowerPC405) processor (revision E0) with 245760K/16376K bytes of memory.

Last reset from power-on

22 Virtual Ethernet interfaces

1 FastEthernet interface

28 Gigabit Ethernet interfaces

2 Ten Gigabit Ethernet interfaces

512K bytes of flash-simulated non-volatile configuration memory.
