Hi again,

I compiled openser trunk (build 3557) and tested it. Same result. Openser
hangs somwhere in a loop or so.

A strace as a wrapper around openser in no fork mode dbug level 4 says
this:

[pid  2829] time([1200923769])          = 1200923769
[pid  2829] write(2, "Jan 21 14:56:09 [2829] DBG:core:"..., 56Jan 21

[pid  2829] write(2, "Jan 21 14:56:09 [2829] DBG:tm:t_"..., 85Jan 21
14:56:09 [2829] DBG:tm:t_lookup_request: start searching: hash=19447,
isACK=0
) = 85
[pid  2829] time([1200923769])          = 1200923769
[pid  2829] write(2, "Jan 21 14:56:09 [2829] DBG:tm:ma"..., 81Jan 21
14:56:09 [2829] DBG:tm:matching_3261: RFC3261 transaction matching failed
) = 81
[pid  2829] time([1200923769])          = 1200923769
[pid  2829] write(2, "Jan 21 14:56:09 [2829] DBG:tm:t_"..., 69Jan 21
14:56:09 [2829] DBG:tm:t_lookup_request: no transaction found
) = 69
[pid  2830] <... select resumed> )      = 0 (Timeout)
[pid  2830] select(0, NULL, NULL, NULL, {0, 100000}) = 0 (Timeout)
[pid  2830] select(0, NULL, NULL, NULL, {0, 100000}) = 0 (Timeout)
[pid  2830] select(0, NULL, NULL, NULL, {0, 100000}) = 0 (Timeout)
[pid  2830] select(0, NULL, NULL, NULL, {0, 100000}) = 0 (Timeout)
[pid  2830] select(0, NULL, NULL, NULL, {0, 100000}) = 0 (Timeout)
[pid  2830] select(0, NULL, NULL, NULL, {0, 100000}) = 0 (Timeout)
[pid  2830] select(0, NULL, NULL, NULL, {0, 100000}) = 0 (Timeout)
[pid  2830] select(0, NULL, NULL, NULL, {0, 100000}) = 0 (Timeout)

the "select" line comes priodically (2-3 times per sec)

I tested it against an umodified (I extended avp aliases for using script
flags) openser 1.4  ... same problem.

Hi Helmut,

i've tried to reproduce this bug on my machine. This config and sip

several permutations of IP and CFGs, unfortunally without any trace to the
