Can't add attributes from large MIBs

Hello,

I'm attempting to gather information via snmp from an F5 load balancer. After I create the SNMP monitor, I go in to add the specific attribute from the F5 MIB. I select the F5 MIB and the attributes show up on the screen as expected. I select the attributes I want and click Add Attributes but nothing is added to the monitor. There are 3 MIBs from F5, 2 of the 3 are 336KB and 234KB in size. The third is 12KB. I have no issue adding attributes from the smaller MIB, but the larger will not work. I even had to use the Admin upload MIB screen to put them on the server because uploading from the Add MIB screen in the MIB browser wouldn't work. Any ideas? Thanks ..
