It's something to do with locking:

open("/usr/home/michael/mount/pw-websites/PW-Websites/baumarkt.de/Website-online
/.svn/wc.db",O_RDWR|0x100000,00) = 3 (0x3)

[...]

fcntl(3,F_SETLK,0x7fffffffbaf0) = 0 (0x0)
fcntl(3,F_SETLK,0x7fffffffc2a0) = 0 (0x0)
fcntl(3,F_SETLK,0x7fffffffc2a0) ERR#11 'Resource deadlock avoid
ed'
fcntl(3,F_SETLK,0x7fffffffc2a0) = 0 (0x0)
write(2,"svn: E200030: sqlite: disk I/O e"...,37) = 37 (0x25)
write(2,"svn: E200030: sqlite: disk I/O e"...,37) = 37 (0x25)

I suspect that sqlite is attempting byte range locking and your server
doesn't support it. I don't know what to do about that.
