[GitHub] [pulsar] w6m6 opened a new issue #8875: garbage collection occured too often

[GitBox]

w6m6 opened a new issue #8875:
URL: https://github.com/apache/pulsar/issues/8875


   **Describe the bug**
   After we upgrade pulsar from 2.4.0 to 2.6.2, we found the frequency of 
garbage collection is much higher than v2.4.0 and the Journal Add latency of 
bookie is increased, which might related to the increase of gc frequency.
