Subject: Problem with oom-killer in memcg
Date: Tue, 26 May 2009 19:04:35 +0900 [thread overview]
Message-ID: <4A1BBEB3.1010701@hitachi.com> (raw)
Hi all,
When I tested memcg, I ran into a problem which causes system hang.
This is what I did.
- make a cgroup named important for memory
- add a process named big_memory into it
- big_memory uses a lot of memory(allocates memory repeatedly)
- big_memory's oom_adj is set to -17
- after a while, the system will hang
Judging from syslog and outputs of console, I think we are in the busy
loop below at that time.
1. oom-killer tries to kill big_memory because of memory shortage
2. oom-killer fails to kill big_memory because of oom_adj = -17
I think it's not good thing that troubles in cgroups affect
all over the system.
Further hardware and software details are found below.
Please let me know if I should provide more information etc.
Regards,

System environment
---------------------------
memory: 6GB
swap : 2GB (partition)
kernel: 2.6.30-rc7
cgroup configuration
---------------------------
group(named important):
memory.limit_in_bytes = 250M
memory.memsw.limit_int_bytes=500M
tasks = big_memroy
processes in the "important" cgroup
------------------------------------
big_memory:
- use a lot of memory(allocate memory repeatedly by malloc())
- oom_adj = -17
syslog output (oom-killer part)
