Looks like i just encountered this issue. I have a sftp host which was unaccessible for some time (ssh connection just hangs). The host started working but I was wondering why the computer felt slow. This is the reason (output from top):

Backtrace of the situation (doesn't look very helpful): (gdb) bt #0 0xb77d6182 in _dl_sysinfo_int80 () from /lib/ld-linux.so.2 #1 0xb739f9db in poll () at ../sysdeps/unix/syscall-template.S:81 #2 0xb74e82db in g_poll () from /lib/i386-linux-gnu/libglib-2.0.so.0 #3 0xb74d96d0 in ??

() I'm not sure if the issue can be easily reproduced but there seems to be a bug. ** Changed in: gvfs (Ubuntu) Status: Expired => New -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gvfs in Ubuntu. https://bugs.launchpad.net/bugs/688700 Title: gvfsd-sftp several minutes consumes all available CPU resources , if try connect to unreachable SSH host.
