- <mcsim> Hi, is that normal that memory cache "ipc_port" is 24 Mb already?
- Some memory has been already swapped out.
- <mcsim> Other caches are big too
- <braunr> how many ports ?
- <mcsim> 45922
- <braunr> yes it's normal
- <braunr> ipc_port 0010 76 4k 50 45937 302050
- 24164k 4240k
- <braunr> it's a bug in exim
- <braunr> or triggered by exim, from time to time
- <braunr> lots of ports are created until the faulty processes are killed
- <braunr> the other big caches you have are vm_object and vm_map_entry,
- probably because of a big build like glibc
- <braunr> and if they remain big, it's because there was no memory pressure
- since they got big
- <braunr> memory pressure can only be caused by very large files on the
- hurd, because of the limited page cache size (4000 objects at most)
- <braunr> the reason you have swapped memory is probably because of a glibc
- test that allocates a very large (more than 1.5 GiB iirc) block and fills
- it
- <mcsim> yes
- <braunr> (a test that fails with the 2G/2G split of the debian kernel, but
- not on your vanilla version btw)

- <braunr> ah great, one of the recent fixes (probably select-eintr or
- setitimer) fixed exim4 :)
