Help: fcsvr_stored crashing/respawning every 15 minutes

Question

Starting at about 0330 this morning, fcsvr_stored has been crashing every 15 minutes with the following CrashReporter log (I've trimmed what I think are the extraneous parts):
Process: fcsvr_stored [30041]
Code Type: X86 (Native)
Parent Process: launchd [1]
OS Version: Mac OS X Server 10.5.8 (9L30)

6 fcsvr_stored 0x0084403e KrKtDecoder::fetchData(unsigned char*, int) + 46
...and so on.
I've run a database vacuum and restarted the FCServer process from the control pannel. Still no love. Anyone have any ideas

Here's a recent one (I've cut off the timestamp and server name for brevity)
com.apple.launchd[1] (com.apple.FinalCutServer.fcsvr_stored[37143]): Exited abnormally: Abort trap
/Library/Application Support/Final Cut Server/Final Cut Server.bundle/Contents/MacOS/fcsvr_stored[38340]: auxpropfunc error no mechanism available

Those three lines were within a second of each other.
Obviously this is related to the device scans. We have lots of Windows Media files on our devices--could this be the cause?
