You have probably memory leak in your server. I'm using Windows XP. Hide Permalink Trond Norbye added a comment - 20/Dec/10 10:55 AM This is an allocation failure, not killed by os....

Please keep open until issue is solved. Thank you very much @pvarley. hamano commented Apr 25, 2014 I understand that difficult to solve this issue. Also, after enabling the watchdog_admins, the following kinds of messages keep appearing: *([email protected]) The process <0.202.0> is consuming too much memory:

I posted the issue for shared information. hope it will save few hours to someone. badlop closed this Jul 11, 2014 Sign up for free to join this conversation on GitHub. Why did Borden do that to his wife in The Prestige?

dirty_foldl(_, Acc, _, '$end_of_table') -> Acc; dirty_foldl(F, Acc, Table, Key) -> Acc2 = lists:foldl(F, Acc, mnesia:dirty_read(Table, Key)), dirty_foldl(F, Acc2, Table, mnesia:dirty_next(Table, Key)). The crash happens after the process starts communicating (sending hi & receiving hello) and this is the only problem I have (by the way, +hms which sets the default heap size I used to rate limit log messages from ports, but then I stopped, which was apparently a bad idea. Conclusion It's probably your fault Do as little as possible inside transactions Use dirty operations instead of transactions Reduce record size Iterate in small batches Share this:TwitterRedditFacebook databasedetsetsiterationmemorymnesiarecordstransactions Post navigation Previous

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). Eheap_alloc: Cannot Allocate Bytes Of Memory (of Type "old_heap"). It's not a perfect fix, since disk can become arbitrarily slow, but it should make it so it just doesn't show up in practice unless things are REALLY screwed up. hamano commented Apr 25, 2014 Nothing in github. You have a slow sender (either C2S or S2S).

  • To access the most up-to-date ejabberd documentation, please visit docs.ejabberd.im » Cannot allocate memory (of type "heap").
  • So now we have 3 copies.
  • So an operation as simple as dict:update_counter("foo", 1, Dict1) consumes twice the memory of Dict1 since Dict1 is copied to create the return value.
  • I then turn on the consumer -to simulate the consumer being unable to contact the broker, or consumer being down for a period etc. - the Akka consumer then starts processing
  • I know an ejabberd 2.0.0 server in a 32bit system with 400 concurrent users consume 1000 MB of RAM.
  • It is very good advice.

What happened to FN-1824?

Prior to this load testing, RabbitMQ worked faultlessly. A major consequence is that when you change a variable or send a message to another process, a new copy of the variable is created. faysou 2016-03-03 08:34:51 UTC #4 It seems to work and this makes sense as the error was a heap error. That table is configured to be stored in disk and also in RAM.

sorry about that. I'll rate limit them. Hide Permalink Trond Norbye added a comment - 20/Dec/10 12:10 PM I ran browse_logs on the system before starting the node again, and this is the output it created. Let's compare that to a dirty operation.

I didn't know about the possible replication issues, which are definitely a big deal in certain environments.

Ulf Recommending dirty operations over transactions should come with a very big caveat: you change the semantics and forego safety, esp.
