Comment 1 for bug 1690723

32bit integer overflow in https://github.com/percona/percona-server/blob/5.7/sql/threadpool_unix.cc#L571
set_timespec_nsec(&ts, timer->tick_interval*1000000);
tick_interval defined as int.

In oracle mysql code thread_pool_stall_limit value is limited to 600 (600M, no overflow for 32bit int):
https://dev.mysql.com/doc/refman/5.6/en/server-system-variables.html#sysvar_thread_pool_stall_limit

Workaround, do not use thread_pool_stall_limit bigger than 2 seconds
