Out of sequence Error

[eironside]

Can someone tell me why I'm getting a sentence out of order error for the following messages?? This error happens on about 10% of my multi-line messages, and appears to be random.

Error is at dk.dma.ais.sentence.EncapsulatedSentence.baseParse(EncapsulatedSentence.java:98) (sorry, markup is affecting the strings, please see the attached text file)

Never mind. wasn't checking the sequence number before sending messages off to be parsed.
