Valentin Kulichenko commented on IGNITE-7993:
---------------------------------------------
[~guseinov], looks like when striped pool is disabled, we simply reuse the
system pool for all tasks that are supposed to belong to striped pool. To my
knowledge this can lead to thread starvation in some cases. Is it possible to
have a separate pool in any case, but just switch form striped to a regular one
if striped is disabled?

> Javadoc for {{IgniteConfiguration#setStripedPoolSize}} states that striped
> pool can be disabled by providing value less or equal than zero:
> {noformat}
> If set to non-positive value then requests get processed in system pool.
> {noformat}
> However, doing that prevents node from startup, it fails with the following
