      Description

      I've just booted 2.6.18-238.1.1.el5.028stab084.1ent on my test server and I'm seeing *lots* for "Uncharging too much" for kmemsize (and only for kmemsize).

      This happens as well on early stage of boot, where there are no CTs started (only CT0) as later, when CTs are running. The amount of messages is staggering, they fill dmesg buffer instantly. I'm attaching /var/log/messages contents, starting from reboot.

      Since it starts to happen even before any CT is up, I don't think that's related to my CTs configuration, but for reference, I am also attaching output of /proc/user_beancounters from 238.1.1.el5.028stab084.1ent (file bcnt.stab84) and 238.1.1.el5.028stab083.1ent, which I've been happily running earlier (file bcnt.stab83).

      If you need any more detail, please let me know. For now, I'm going back to stab083.1 as this uncharging too much is filling up my logs.

        Thanks. First impression is better - 3 minutes uptime with your test kernel, and so far no problems. I'll run this kernel for a while and report back any issues.
