libss7 BLO / BLA issues (audio loss, call drop, asterisk hangs)

Hi,

I have a strange issues with BLO / BLA functionality... Could somebody 
be so kind and check it, where's the problem?

libss7-trunk (r320), with asterisk-trunk-r372092 with SS7-27 patches..
the same applies also to svn /team/rmudgett/ss7_27_knk (r380912M-/trunk)....


make call from SPC 1 -> to SPC 2, answer at SPC 2
now block this CIC or linkset, at SPC 1 (call origination side)
- call audio is stopped (should not be)
- call cannot be cleared (REL is retransmitting)
- SPC 1 remains OK, will connect another calls
- SCP 2 becomes totally unusable...  one way audio at next call, not 
connecting other calls at all, "core restart now" hangs.... requires 
kill  -9 `pidof asterisk` to resume operation

make the same call from SPC 1 to SPC 2, answer at SPC2
but now block this CIC or linkset at the opposite side, at SPC 2 (call 
termination side)
- call is dropped (should not be)
- SPC 1 remains OK, will connect another calls
- SCP 2 also remains OK.....

good way to check if asterisk already hanged
# asterisk -rx 'ss7 show channels'
if hanged, this output hangs too, just on the CIC with broken (blocked) 
call...

Any help would be appreciated....

Thanks,
M.R.
