Getting increase EVENT_POOL_SIZE error with PROBEMGR queue?

Has anyone seen this error on their ND7 server:Event: Error posting event to event queue ‘PROBEMGR’: Insufficient memory - event pool is full. You can increase it’s size via the NOTES.INI setting EVENT_POOL_SIZE

The size is already 20MB. The servers this is happening to are our first ND7 servers that are lightly loaded. I will increase the size but I would like to know if this may be an issue.

Thank you,
