Comment 63 for bug 1124250

Dariusz:
Today the problem has occurred again:
sudo cat /proc/key-users
    0: 65 64/64 58/200 810/20000
and the /var/mail folder was hit in this case.
After a while (about 1 hour) the problem diminishes with the following key-users result:
   0: 21 20/20 14/200 194/20000
As I don´t understand the meaning of this values, I don´t know what values I should use.
We have a ldap/krb5 setup with 30 users and 15 groups.
The kernel was
Linux version 3.13.0-51-generic (buildd@tipua) (gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5) ) #84~precise1-Ubuntu SMP Wed Apr 15 21:45:46 UTC 2015

Thanks Stef
