.NET java thread count keeps growing
Hi!
I have growing java thread count. The application crashes with OOME. The
application is very simple, only reading values in a cache.
Any suggestion to debug this issue?
Ignite 2.4

Good news, everyone, I've found a straightforward fix for this,
cross-platform and in pure C#.
Will be included in Ignite 2.8. Details in the ticket.

Re: .NET java thread count keeps growing
Posted by Pavel Tupitsyn <pt...@apache.org>.
Denis, the problem is described in
https://issues.apache.org/jira/browse/IGNITE-9638
It is not specific to Continuous Queries.
It occurs when user code starts new threads a lot and calls Ignite APIs
from there (which is not common, since idiomatic .NET code should use
built-in thread pool instead).
I investigated it thoroughly last year and, unfortunately, did not find a
clean, cross-platform solution - see my comment in Jira.
We'll have to develop a fix for every platform (Linux, Windows, Mac)
separately in C or C++, compile native binaries and ship them as part of
Ignite.NET or as a dependency.

Ilya, thanks for bringing up the discussion.
Pavel, did you have a chance to asses the problem? Is it specific to
asynchronous CQ (as reported on SO) or spans across many APIs?

We have observed a similar problem but have not characterised it well
enough to report on the list yet.
We are using IA .Net 2.7.5.

Denis,
Can't say for sure, did not investigate this yet. I'll try to find time
next week and get back to you.

Pavel,
Do you think we can get it fixed in 2.7 time frame?

Hi, I found a way to reproduce the issue.
I think it is related to .net thread identity.
New .net thread leads to new java thread.

Hello!
You seem to have 3000 threads of form "Thread-NNNN", which is not what
Ignite usually uses, and they're all empty.
This is mysterious so I urge you to share the sample reproducer (or,
barring that, code snippet) that leads to such behavior.
By the way, do you observe any errors in the log?
