It sounds like you have exceeded the limits of the flow table.

Try raising “forwarding-options sampling instance sample-ins1 input rate" to 500 to see if you reliably get flows again.  If so, you can gradually step the sampling rate down to a level that reliably handles your traffic, or add an MS-MPC to increase inline jflow capacity if you really do “need” 1:1 sampling. Depending on your needs, sampled flows may be totally adequate.
