Fdb::fdb_exception (CommitProxy commit memory limit exceeded)

Error code 1042 appears when I perform FDB pressure testing. At this time, the cluster is unavailable. The status json information is as follows:

sing cluster file `/etc/foundationdb/fdb.cluster'.
 
The database is unavailable; type `status' for more information.
 
Welcome to the fdbcli. For help, type `help'.

When the pressure test is stopped, the cluster automatically returns to normal. How to avoid this situation?
