Hello,
We have an ignite cluster of 3 nodes (16GB RAM, 50GB disk space each)and
have given 10GB (off-heap) to data region and (Xms) 2GB and (Xmx) 3GB to the
nodes.
One node went down and while restarting the node, I get the exception that

I've been having problems recently with nodes crashing out of a running,
18-node cluster. I managed to catch the following error log out of one of
them. Unfortunately I did not manage to grab the core dump before the AWS
instance was destroyed. I'll try to grab one if I can.

Hi,
Could you tell me something about my problem?
Before OOM error I was getting warning messages such as "Failed to unmarshal
node metrics:".

Hi,
Thank you for the hint. I just wrote a small program to allocate 1 GB
memory and to free the same memory using UNSAFE api. I took the native
memory tracking report 3 times, before allocating 1 GB memory, after
allocating 1 GB memory and after freeing 1 GB memory.
Here is the snippet of report

Hi Prasad,
As far as I remember offheap memory allocated with use of Unsafe is
not reflected in Native Memory Tracking report. You are right that
documentation is not verbose about reported categories [1]. It might
be the case that memory allocated by ByteBuffer.allocateDirect falls
into "internal
Hi Support,
I am using cfg.setAtomicConfiguration() function, but I find there is no
enum type for AtomicConfiguration.
Only CacheAtomicityMode is available in Java doc. But it could not be used
in cfg.setAtomicConfiguration()
It is contradiction.
Please advise what I am missing.
Thank you.

Hi.
Please don't use posting to both dev/user lists simultaneously.
If your question is not related to any contribution you are planning to do,
then the user list is a better place to ask, because a possible answer may
be interesting to all Ignite users.

Hi,
I have set the off heap size to 500 MB and max heap size to 512 MB.
My process is taking around 1.7 GB on Windows 10 as per the task manager.
So I decided to track the memory distribution using jcmd to find out if
there are any memory leaks in non-heap space.
After pushing the data to cache
Hello!
Please note that SecurityContextHolder is thread-local.
You might need to have a fixed instance of SecurityContext in your
processor as opposed to getting it from holder when you don't need thread
locality.

I guess you will have to fill this context yourself for calls which supply

Hello!
1) The best way of preloading data is to add CacheLoader (or CacheStore) to
cache configuration and call loadCache().
2) Data will be collocated as long as both caches use same affinity field
(via annotation, AffinityKey or configuration).
Then if you join tables by that field Ignite will
Hello!
I recommend starting from simplest configuration to more complex one.
Remove onheap cache, see if problem goes away.
