We experienced performace issue due to Polls for Confluence

Description

Hi Team,

We experienced issue in our confluence which is hosted behind data center version with two active nodes goaazraoo075(Admin Node) & goaazrapp076(Node1) .

We had captured the required logs during the issue and shared the same with Application vendor (Atlassian) via a ticket PS-29645 in order to find the exact root cause of the issue .

they responded that "There is only one method in thread which indicates what the problem is

"catalina-exec-192" #27511 daemon prio=5 os_prio=0 tid=0x000000005a5f0000 nid=0x2de8 runnable [0x000000019aec3000]

The thread shows a plugin being loaded, attempting to make a database call, then becoming stuck waiting for the database transaction to complete.

It turns out this is a known bug, that was fixed a few days ago.

CONFSERVER-45363: The Workbox's setPingCompleted method is susceptible to deadlocks (fixed in Confluence Server 6.11.0) "
The use of the Polls for Confluence plugin increases the number of interactions which increases the chance of encountering the issue.
The plugin provides polls which are provided through the Workbox notification plugin.

We have some query regarding the above issue .
1 Is the above issue is related to this ticket https://bitbucket.org/simplenia/polls-for-confluence/issues/76/unable-to-create-and-save-polls-in

2 If we will upgrade the polls plugin as recommended in last ticket ,will this version help us to avoid the issue which happended due to above cause?

Your reply will be appreciated .

Thanks
Suraj
