sschepens opened a new issue #1737: Bookies at 100% CPU
URL: https://github.com/apache/incubator-pulsar/issues/1737
 
 
   We're experiencing apparently the same issue that we reported at #110
   We having most of our bookies hang at 100% CPU while reading from rocksdb, but our disk metrics show little to no reads on the disks which is strange.
   
   We're running pulsar 1.20 and bookkeeper version 4.3.1.72-yahoo.
   
   Here is a jstack from a bookie:
   
   [jstack.txt](https://github.com/apache/incubator-pulsar/files/1977178/jstack.txt)
   
   Our bookkeeper config is the following:
   
   [bk.conf.txt](https://github.com/apache/incubator-pulsar/files/1977179/bk.conf.txt)
   
   This is currently affecting one of our production clusters and don't really know how to mitigate it.
   
   @merlimat @sijie do any of you know how to mitigate or fix this, this is of course an issue with the rocksdb storage of bookkeeper.
