[jira] [Commented] (TS-1375) too many connections, throttling
Posted by "kuotai (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/TS-1375?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13423648#comment-13423648 ]
kuotai commented on TS-1375:
----------------------------
This bug is because of one or more net thread is in lock_wait state(because of mutex is not unlock). So the hunged net thread will accept new event from scheduler, but can't handle event. One new client will create one connection(will create one event), but the connection havn't be processed(mean close connection). Now, we have found one case in cluster, be testing more about my patch. And I think every unlock mutex about connection maybe trigger connection's throttling.

[jira] [Updated] (TS-1375) too many connections, throttling
Posted by "Leif Hedstrom (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/TS-1375?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Leif Hedstrom updated TS-1375:
------------------------------
Fix Version/s: 3.3.1
Kuotai: Is there another bug related this? If so, make sure we only have one.
Also, I assume this is the same issue you showed me in Hangzhou? The warnings themselves are expected, what's not expected is to run out of sockets / FDs unless you truly have a large amount of connections (i.e. what you showed me looks like a "leak").
