Yes, the clients are doing lots of creates. But my question is, if this is a memory leak, why does ocfs2 eat up the memory as soon as the clients start accessing the filesystem. Within about 5-10 minutes all physical RAM is consumed but then the memory consumption stops. It does not go into swap. Do you happen to know what version of ocfs2 has the fix? If it was a leak would the process not be

Hello I''ve got a server with 3Gb of ram and I want to keep 256 for the system and allocate the rest to conntrack ...

i just got a ''ip_conntrack: table full, dropping packet'' because a p2p-application ran amok. i''ve killed the process but /proc/net/ip_conntrack still got more than 7000 (now stale) entries of 8184 max. since the table is now after ~70 minutes down to 6995 entries, i wonder if i can flush this table manually. the entries in there look like tcp 6 155674

Hi, my ip_conntrack table is filling up and now my server is dropping packets. I'm running CentOS release 4.4 (Final) on a fairly busy webserver. The table is full of various connections, including a lot of "ESTABLISHED" tcp connections from my webserver (the src is my webserver ip), and some other random connections to my webserver, and many "ASSURED" connections. So why

Under both XEN 3.0.4 (2.6.16.33) and XEN 3.1 (2.6.18), I can make the OOM killer appear in dom0 of my server by doing heavy I/O from within a VM. If I start 5 VMs on the same server, each VM doing constant I/O over its boot disk (read/write a 2GB file), after about 30 minutes the OOM killer appears in dom0 and starts killing processes. This was observed using 256MB in dom0. If I bump the memory in

Hello, Should "route -C" show the RTCF_REDIRECTED flag ? (0x00040000). I had searched in the code and it seems that it should show this flag by "r". However, I could not show this flag by "route -c " even that it should have been there. I have the following scenario where I have this flag set. I see it in cat /proc/net/rt_cache but **not** in route -C. (BTW,

I''ve been having all sorts of problems the last few days with my connection slowing down and then stopping working. Rebooting the router box always fixes it for a while. When I couldn''t hit any pages this morning, and couldn''t even ssh into the router, I dug around a little. When I did a dmesg on the router, there were a bunch of errors saying: ip_conntrack: table full,

It seems that the value of net.ipv4.ip_conntrack_max has no so much to do with the conntrack ''cause the when I measure current number of connections i.e.: wc -l /proc/net/ip_conntrack they show as ~20-30 000 connection, but I set sysctl -w net.ipv4.ip_conntrack_max=150000 and packets get dropped, I have to set it to value above 200 000 so that packets are not dropped ?!! Any idea

I have a bunch of servers, where I''ve deployed shorewall-lite. For us is very useful to have a centralized repository of the firewall rules deployed in our servers.

Hi all, i need advice how can i limit ip_conntrack per IP. clients of network that i support often uses torrent , DC++ , eMule clients and i have lost packages because they open too many ports. i have traffic control limits but this obviously isn''t enough Any advance how to prevent server from this kind problems will be welcome.

Hello, I've just run out of memory on a dual xeon with 5GB ram, considering there should have been around 4GB free (not counting buffers and cache)... this is unusual. Now after it OOM'ed I tried running top and memory usage was fine (around 1GB of 5, no swap usage of 12GB). So I thought it was a temporary thing, but processes kept on OOM'ing for no understandable reason... while
