VNXe3150 SP reboot problem caused by internal DB error

Greetings, We've got some VNXe3150 and periodically send uemcli queries to SP to check hardware status of the storage.

The problem is that the SP service restarts from time to time and EMC results it is caused by internal DB error occurred during its vacuum process. As EMC has no plan to release updated OE for this problem, we truncate DB data to reduce the usage of /EMC/backend/log_shared filesystem about once every month which requires engineering fee for the onsite job.

Now the question is that if there is any good idea to stop increasing of the filesystem usage.

Any kind of comment is welcomed.

Thank you.
