Rabbitmq Eheap_alloc Cannot Allocate


the allocation request is low: 1-4 MB 2. example() -> Var1 = mnesia:dirty_read(example_table, "foo"), Var2 = update(Var1), ok = mnesia:dirty_write(Var2), Var2. zinid reopened this Apr 25, 2014 ProcessOne - XMPP, Erlang, jabber member zinid commented Apr 25, 2014 Now you should provide something more than PNGs or I close the ticket. this is crashdump information: Slogan: eheap_alloc: Cannot allocate 4454408120 bytes of memory (of type "old_heap"). his comment is here

Rabbitmq Eheap_alloc Cannot Allocate

if you have a replicated system. Now it's quite annoying as my application hasfew bugs left but the database crashes, and I'm not qualified to debug it. Here's how to fix it. Is it possible/likely this is due to large m/r requests?

Prior to this load testing, RabbitMQ worked faultlessly. We're running the following dedicated bare metal setup for our rabbit boxes: "Debian GNU/Linux 7 (wheezy)" Linux rabbithostname 3.2.0-4-amd64 #1 SMP Debian 3.2.60-1+deb7u1 x86_64 GNU/Linux 64gig of ram free -l total How can I track time from the command-line? As far as I can tell crashing doesn't seem to > coincide with any particular requests to Riak.

As I don't have a definite solution to your problem, I'll give you some random comments, in the hope that one of them helps you. share|improve this answer answered Sep 29 '14 at 14:11 Igor Berman 606310 add a comment| up vote 1 down vote You ran out of memory. Erlang is a functional language with single assignment and no shared memory. You already know the answer and keep trying to get the confirmation.

The size of the writes is always between 40 and 70 MB/s - only frequency of their occurrence is changing (currently it is 1 per hour, yesterday it was every 5 Skip to content Ignore Learn more Please note that GitHub no longer supports old versions of Firefox. If the size of the record grows by 1 byte, then each transactional operation like the above will require an additional 5 bytes of memory, or dirty operations will require an Inserting temporary objects and forgetting to delete them is a fairly common source of memory growth.

Why is innovation spelt with 2 n's while renovation is spelt with 1? Abnormal termination". Please reopen due to issue has not been solved at all. weblink Does it relate in any way to the Hipe plugin?

Anyway issue is in your server code. The filesystem type is ext3, and it is mounted as: rw,noexec,nosuid,nodev,noatime,nodiratime,commit=1. Doing it dirty results in only 4 copies: the original Var1 in example_table, the copy sent to your process, the updated Var2, and the copy sent to mnesia to be written.

So now we have 3 copies.

Everyday after about a day of activity the server crashes and the only way to make it workagain is to restart Windows.The same used to happen with Couchbase 4.1. I don't care close the issue. One very simple such device would be a gen_server that workers ask (synchronously) for permission before starting a new task. The test machine is Windows 8, 4 cores, 8 GB Ram, running Erlang R16B and YAWS 1.6.

The process crash by external input is jsut a bug, but VM crash is vulnerability. I've increased it and will report here if this solves the problem or not within a few days (this is the scale of the problem). Is there any way to limit the memory usage in XML parsing? http://outwardsound.com/cannot-allocate/cannot-allocate-memory-in-linux.html Ya, I don't know which process try allocating 4G memory.

Cheers. You have probably memory leak in your server. Also, after enabling the watchdog_admins, the following kinds of messages keep appearing: *(ejabberd@localhost) The process <0.202.0> is consuming too much memory:

In my experience, the "iterate in small batches" should be one of the first points. Without looking into the full dump it's hard to say the exact reason.

Dirty operations like this will generally have 2/3 the memory footprint of operations done in a transaction. What bothers me is: 1.

Even if your processes doesn't consume that much memory, you'll waste a lot of it anyway. –Adam Lindberg Jun 27 '12 at 7:00 add a comment| up vote 1 down vote We recommend upgrading to the latest Safari, Google Chrome, or Firefox.
