[asterisk-users] Maximum retries exceeded on transmission

I confirm the same behaviour. I use asterisk with Mera Softswitch (with
SIP HIT).
After upgrading from 1.2.13 to 1.2.14 "Maximum retries exceeded..."
messages began to appear in logs. About 10% of calls were lost. I've
dumped such calls and don't see anything suspicous in Mera's packets.
Asterisk doesn't reply for first several INVITEs from Mera but then it
replies OK, Mera sends back ACK but it seems that asterisk ignores it
and tries to send OK. After trying to send OK several times asterisk
hangs up the call. I've attached the text file where this can be seen.
Mera SS is 10.150.16.4. We see that asterisk replies to INVITEs after 4
seconds. That's wierd. Server is not heavily loaded - about 10
simultanious calls.
I've downgraded to 1.2.13 and problem has gone away. I guess there is
something wrong with asterisk.
Regards.
Andrey Solovjov.
