Hi,

Hopefully I found and fix the problem - see this fixing patch:
    https://gist.github.com/bogdan-iancu/2875ae7cc99a2180463d

Apply it together with the prev one (just in case).

Hi:
     that error come out again.
     I doubt  there have memory leak.  that server have   32G memory.
     the opensips config:
     default Start option    S_MEMORY=4096  and  P_MEMORY=128
     children(process)       128
     then I think opensips   have 4096 + 128*128 = 20480M memory, this is
right?
     opensips hold memory never free ,  top command result:
