there was a server update today that fixed my crashing and freezing. 

Here be the patch notes for the latest server update:

"We have just distributed a new server version named R7 to the server hosts. Early signs from the hosts are good with 20% less load on the server CPU, improved hit detection, Veteran rank handling is fixed so you should get your M1 Garand back now plus some other fixes to better help the server hosting companies and better management of Punkbuster IDs."

All dedicated servers are currently patching to the new server build just released by DICE, R7, which has quite a few fixes:
- Several common crash fixes. Especially those which have monitoring scripts that rely on the Remote Admin interface should see stability improvements.
- PunkBuster can send commands to Remote Admin interface (so ‘pb_sv_task 0 -1 ’ works)
- Veteran-rank handling corrected (it was broken in R6 and possibly earlier)
- Switched back to Release version of the low-level networking library; less debug output but higher performance
- Increased the initial server reconnection interval to 30+rand(30) seconds
- PB GUID generation is now based on EA account IDs (it used to be based on persona names)
- Added new command line options which allow providers to easily maintain server GUID's
