When trying to Configure a MSDP disk pool on a system with a large amount of physical memory an error is received during the 'Configuring Media server deduplication pool' stage of the wizard. The issue occurs when spoold is initializing the cache with a bits setting that is higher than a support number. Spoold currently supports a maximum of 28bits and in an environment with more than 170GB of RAM it is possible that spoold will use 29bits.
MSDP Configuration pop-up error:
Database system error . RDSM has encountered an STS error : failed to update storage server configuration due to unsupported platform ,invalid configuration or system error.
Warning: manually modifying PureDisk services can cause unexpected behavior!

ERROR: starting spoold failed
The following can be seen in a spoold trace:
# spoold -v --trace
Info: Auto-sized value for /Storage_path/etc/puredisk/contentrouter.cfg: section Cache, entry Bits to 29 bits
The maximum bits support currently is 28bits.
The following line will be see before spoold crashed:
Trace : StorageDBOpen: done
Trace : CacheInit: bits = 29
Segmentation Fault (core dumped)
The issue occurs because during setup Netbackup tries to configure a cache for MSDP based on the amount of physical RAM . If the System has a large amount of physical RAM the the cache initialization will fail. In this instance the customer had 256GB of RAM .
