my thread got closed

I had a thread open and now it says it's closed. I had a question still on the forum and about 15mins after I posted my most recent question on it the thread said "closed". Why did this happen? I didn't violate any forum rules. Is there a limit on how many postings you can have in a single thread?
Thanks

I closed it.
