There is no strict limit on the number of pins in a multicast limit. However, there is a limit on the push size of 8KB. There is also, at least for BES Push, and most likely also for BIS Push a limit of 3KB on the headers of a push.
So in practice there is a limit on how many addresses you can put in a single multicast push, because the more addresses you include, the larger your message will get. The size of your content will have another significant impact on the number of recipients. You'll have to determine what number works based on your data, but you can likely do 100-200 pins with a reasonable amount of content.
If you exceed either limit, the server will close the connection, so in that case, try with fewer pins and make sure your content is within the limit as well.
