[Samba] extremely high %CPU and TIME

[Tom Ryan]

I've kept looking for an answer to this to no avail.. any ideas?

strace -p  reveals

fcntl64(14, F_SETLKW64, {type=F_UNLCK, whence=SEEK_SET, start=684, len=1}, 
0xbffff180) = 0
fcntl64(14, F_SETLKW64, {type=F_WRLCK, whence=SEEK_SET, start=684, len=1}, 
0xbffff150) = 0
fcntl64(14, F_SETLKW64, {type=F_UNLCK, whence=SEEK_SET, start=5676, 
len=1}, 0xbffff160) = 0
fcntl64(14, F_SETLKW64, {type=F_UNLCK, whence=SEEK_SET, start=684, len=1}, 
0xbffff150) = 0
fcntl64(14, F_SETLKW64, {type=F_WRLCK, whence=SEEK_SET, start=688, len=1}, 
0xbffff150) = 0
fcntl64(14, F_SETLKW64, {type=F_UNLCK, whence=SEEK_SET, start=688, len=1}, 
0xbffff150) = 0
fcntl64(16, F_SETLKW64, {type=F_RDLCK, whence=SEEK_SET, start=528, len=1}, 
0xbfffda40) = 0
fcntl64(16, F_SETLKW64, {type=F_UNLCK, whence=SEEK_SET, start=528, len=1}, 
0xbfffda40) = 0
time(NULL)                              = 1069272774
fcntl64(16, F_SETLKW64, {type=F_RDLCK, whence=SEEK_SET, start=548, len=1}, 
0xbfffc8a0) = 0
fcntl64(16, F_SETLKW64, {type=F_UNLCK, whence=SEEK_SET, start=548, len=1}, 
0xbfffc8e0) = 0

thanks!
