Network is not working with pfil module inserted

Hello

Interface stops working after short period of time when pfil module is
inserted into modlist. Here is status of pfil output :

# ndd /dev/pfil qif_status
ifname ill q OTHERQ
ipmp num sap hl nr nw bad copy copyfail drop notip nodata notdata
ce700000 0x3000218f628 0x3000337f388 0x3000337f468 0x0 27329 800 14
55 88 0 0 0 0 34 0 0

"nr" stops increasing, "nw" keeps increasing and "notip" starts
continuously increase when network flow stops.

Any ideas how this can be solved ? pfil documentation is not good enough
to find out what problem can be behind this.


With best regards
