What version are you using?
How many retries do you have set?
It could be your news server is late to get parts so, if you use search or NZB files, the posts really aren't there yet. 2 retries which is the default is something like 30-60 seconds of waiting which means if the problem really is that your server is slow to get parts, you might need more retries so it keeps trying until the server gets the parts.
Without looking at it I can only guess.
