Re: Subversion stalls

Hi,

some more infos on the stalling of 'svnadmin verify path/to/repository'

Here's the result of 'strace svnadmin verify path/to/repository'

open("path/to/repository/db/representations", O_RDWR) = 9
fcntl(9, F_SETFD, FD_CLOEXEC) = 0
fstat(9, {st_mode=S_IFREG|0775, st_size=704512, ...}) = 0
lseek(9, 0, SEEK_SET) = 0

(the last line gets repeated about every second)

here's the output of gdb's where:

So it seems that the database waits for another thread... any tips to
resolve my issue?

TIA,
