   > It can be reproduced stably, as long as there are enough news accumulated。You can reproduce it yourself. The phenomenon at that time was that when the message accumulation reached about 30 million, the java process occupied more than 20G of memory, and the master would not respond for a period of time. I guess it is because the accumulation of messages exceeds the memory size and there will be a pause for a while.
   
   I will try to reproduce the issue.
   In addition, does this issue exist in the lower version of the dledger?
