com.mchange error leading to jira slowness

[Sijo kurien]

We have been encountering jira slowness in one of our client installation,

 We have a custom plugin added in jira.

We found the below exceptions in the catalina.out,

/cxps/atlassian/jira/logs]grep -i exception catalina.out
com.mchange.v2.cfg.DelayedLogItem [ level -> FINE, text -> "The configuration file for resource identifier '/mchange-log.properties' could not be found. Skipping.", exception -> java.io.FileNotFoundException: Resource not found at path '/mchange-log.properties'.]

com.mchange.v2.cfg.DelayedLogItem [ level -> FINE, text -> "Missing or empty HOCON configuration for resource path 'c3p0'.", exception -> null]

Can anyone please help us why this is occuring? Any lead would be helpful. Thank you.

Sorry this is not an answer, but can someone help us here. We are analyzing a jira slowness issue and we need to ensure this logging doesnt lead us to anything or otherwise.
