com.splunk.hecclient.HecException: linked blocking event queue is full, failed to offer batch into queue

[waewoo]

Hello.
​
I regularly have this type of error (linked blocking event queue is full), which is then followed by an error concerning a java memory problem (Posting Resource Exhausted event: Java heap space) ... which then causes the connector crash.
​
What could have caused this type of error? What parameters need to be changed to avoid this type of error?
​
thank you
