Applying large quantities of legal holds simultaneously will cause the StorageOnlineOpns process to consume memory until the Enterprise Vault services become unresponsive.
Regulate the quantity of legal holds being applied at any one instance in order to control the memory leak.
- As legal holds are being applied, the StorageOnlineOpns will consume memory and will continue to consume additional memory until the legal hold work for the case is complete; at which time the StorageOnlineOpns process is terminated and the memory released back to the application pool. Legal holds for the next case can be applied. These steps are to be repeated until all cases requiring legal holds have been completed.
This issue has been addressed as part of the following release:
