Throttle Scalix Indexer Service

After an upgrade of scalix you may find that the load of the server is quite high.
Its the Search and indexing service re-indexing all email for SWA. This is normal behavior.
While its normal, its certainly not desirable, especially if you've got a large mailstore or have upgraded during the day. To get around this high load you can throttle the indexing service.
vi /var/opt/scalix/XX/s/sys/general.cfg
Add the following lines, the comments are just for reference....
# Throttle the mailbox indexing service to avoid system crash # where xx and yy are per-CPU load averages. The IDX_MAXLOAD setting # will stop the indexer from indexing any further messages when the # per-CPU load average goes above the defined value. The indexer will # not resume indexing until the per-CPU load average goes below the # value defined by IDX_MINLOAD. IDX_MAXLOAD=6 IDX_MINLOAD=2
Save and quit. Restart scalix to affect the change.
service scalix restart
Of course you can use your own values to suit your environment.
