Repeated regular AFP crash

All, I'm getting a regular AFP crash regularly for weeks now, and after looking over all the crash logs, the thread that brings it all down (Bus Error) always crashes with the following: 0 AppleFileServer 0x0004bd51 ByteRangeLockTreeKey::~ByteRangeLockTreeKey() + 4607 1 AppleFileServer 0x0006493f FPVol::MapCatInfo(FSCatalogInfo*, FSRef*, HFSUniStr255*, unsigned char) + 27891 2 AppleFileServer 0x0006d357 FPVol::MapCatInfo(FSCatalogInfo*, FSRef*, HFSUniStr255*, unsigned char) + 63243 3 AppleFileServer 0x00071529 FPVol::MapCatInfo(FSCatalogInfo*, FSRef*, HFSUniStr255*, unsigned char) + 80093 4 AppleFileServer 0x00071716 FPVol::MapCatInfo(FSCatalogInfo*, FSRef*, HFSUniStr255*, unsigned char) + 80586 5 AppleFileServer 0x00076956 UserStatusTask::Run() + 8160 6 AppleFileServer 0x00079311 SharePointSyncTask::~SharePointSyncTask() + 4547 7 AppleFileServer 0x00045748 OSTree_Protected::~OSTree_Protected() + 5460 8 AppleFileServer 0x000443a5 OSTree_Protected::~OSTree_Protected() + 433 9 AppleFileServer 0x0004447f OSTree_Protected::~OSTree_Protected() + 651 10 libSystem.B.dylib 0x96b20095 _pthread_start + 321 11 libSystem.B.dylib 0x96b1ff52 thread_start + 34 Any ideas?
