> Key: IGNITE-9244
> URL: https://issues.apache.org/jira/browse/IGNITE-9244
> Project: Ignite
> Issue Type: Bug
> Reporter: Dmitriy Govorukhin
> Assignee: Dmitriy Govorukhin
> Priority: Major
> Fix For: 2.7
>
>
> In the current implementation, GridDhtPartitionsEvictor reset partition to
> evict one by one.
> GridDhtPartitionsEvictor is created for each cache group, if we try to evict
> too many groups as sys pool size, group evictors will take all available
> threads in sys pool. It leads to hangs send a message via sys pool. As a fix,
> I suggest to limit concurrent execution via sys pool or use another pool for
> this purpose.
