<p>The increase of memory is very likely the side effect of
processes not handing the traffic, sip_msg_shm_clone() is manly
used when creating the transactions. They can accumulate if the
timer processes are stuck or other callback functions block the
transactions hash table. As said in the other email, try to get
the output of kamctl trap to have information about what all
processes do at that moment.</p>
