Hi,
When load testing the write operation against Zookeeper 3.7.0, I observed a couple of times that the server crashed because the txn log was too large and it was not able to load it. However the data size of write is only 4 bytes in the load test and the *jute.maxbuffer *was set to default (i.e. 1M). The error doesn't always happen. I wonder if anyone has also seen this error or has any idea on what may cause the issue?
