--------------------------------------
Summary: Add "onSpinWait" to timestamp updater thread
Key: IGNITE-25494
URL: https://issues.apache.org/jira/browse/IGNITE-25494
Project: Ignite
Issue Type: Improvement
Reporter: Ivan Bessonov
Assignee: Ivan Bessonov
Following problem occurred while local testing (with safe-point timeout being 1
second):
{code:java}
[118.719s][warning][safepoint] # SafepointSynchronize::begin: Timeout detected:
[118.719s][warning][safepoint] # SafepointSynchronize::begin: Timed out while
spinning to reach a safepoint.
[118.719s][warning][safepoint] # SafepointSynchronize::begin: Threads which did
not reach the safepoint:
[118.719s][warning][safepoint] # "FastTimestamps updater" #184 daemon prio=5
os_prio=0 cpu=331.99ms elapsed=116.07s tid=0x00007f88a4004370 nid=0x1fb52d
sleeping [0x00007f887e9fe000]
[118.719s][warning][safepoint] java.lang.Thread.State: TIMED_WAITING
(sleeping)
[118.719s][warning][safepoint]
[118.719s][warning][safepoint] # SafepointSynchronize::begin: (End of list)
{code}
Apparently, it can be alleviated with forcing a safe-point into the loop. One
way of doing that is using "Thread.onSpinWait()". Let's do it and then see if
the problem persists.
