[fuse-devel] FUSE memory leak?

[Dmitry E. O. <un...@de...>]

I've encountered such a problem.

When mounting a catalogue with the help of  FUSE,  then  the  amount  of
memory used by FUSE process increases gradually.

More detailed analysis of the problem has lead me to the  fact  that  in
truth FUSE (and it doesn't depend  on  the  type  of  file  system,  the
results are approximately the same everywhere) doesn't finish the  tread
after it isn't needed any more.

For example a few days  ago  I  used  sshfs,  and  today  the  foolowing
situation can be seen:

nbw:[~]$ ps -eLf|grep sshfs
root      3912     1  3912  0    3 Jun23 ?        00:00:00 sshfs dimka@dgate:/share/common /share -o rw,nosuid,nodev,IdentityFile=/root/dgate,allow_other,default_permissions,reconnect
root      3912     1  3913  0    3 Jun23 ?        00:00:00 sshfs dimka@dgate:/share/common /share -o rw,nosuid,nodev,IdentityFile=/root/dgate,allow_other,default_permissions,reconnect
root      3912     1  3914  0    3 Jun23 ?        00:00:00 sshfs dimka@dgate:/share/common /share -o rw,nosuid,nodev,IdentityFile=/root/dgate,allow_other,default_permissions,reconnect

So three threads have been opened for some days already.

It would not matter, but when starting a program,  creating  rather  big
file activity, then there  may  appear  a  great  amount  of  unfinished
threads (I've seen up to 15), and if every thread uses a few  (sometimes
up to 10-15) megabytes then FUSE "eats up" too much memory  (and  it  is
very important for my micro-server with rather small amount of memory)

Is it possible to  mount  with  some  options  (may  be  to  change  *fs
programme) so that non-active threads are finished automatically?

PS: I've made tests on 2.4.18-2.4.25 systems and the result is the  same
everywhere.
