Hi Jeff,
Is this with B2BUA?
I have a report with a complex b2b scenario and transactions hanged in
memory.

Hello,
Everything is running along just fine for weeks on 1.6.4, and then
/bam/, this shows up in the logs:

Hundreds of lines like it. This is just a sample. But, it did not
crash. I have shared memory set to 32M. Normally I run less than 8M
used. After this event the max_used_size was at 32M, but the
real_used_size was around 24M. And it wasn't changing. Strange.
My first thought was a DoS attack but a pcap I took right after looked
normal.
Normally this proxy runs anywhere from 70-150 transactions in progress
at any given moment. After this event, it was stuck at right around
1300. Things seemed to be processing; no symptoms on outbound calls.
Very strange.
I restarted Opensips and everything seems normal.
I'm not sure where to begin on this one. I'm not sure if the shared
memory problem was a symptom or a cause. In the few years I've been
working with Opensips I've never seen anything like this. Any
direction from the list would be great.
