Hi George,
looking over the log, it does seams to be a leak. My guess is that there is too few PKG memory configured. 
                          ^^^^^ doesn't !
You have probably a large script and some intensive message processing which may result in mem outage at a point. Also memory fragmentation may increase the memory usage. 

Try to increase the PKG memory and see if you get rid of the problem.

Hi Bogdan,

Bad news, I am afraid. I got another "out of memory". I did another
memory dump on process 10714 this time. Actually there is one dump that I did earlier to see if there were any 
segments allocated by subst_str.
And I did a second dump after the "out of memory" happened. The log file
is:

thank you

George

Hi George,

Hi Bogdan,
The server has been running for about 18 hours without any "out of memory" messages. Usually these appeared after a few hours.
I think it 
is fixed, but I will keep you posted if it reappears. Thanks a lot!

That is super! I will commit the patch on SVN.
I guess the same fix needs to go in subst_uri() and maybe
also add a 
check if(result->s!=0) ?
well, in subst_uri() there is no need because the result->s chunk is transferred to msg->new_uri (and freed later from there); in subst_user(), the result->s chunk was copied by the SET_USER_T action, so we need to free it also.
Why did this only appear on the first receiver child? I
would expect
that all children receive an equal amount of traffic so they should all run out of memory more or less at the same time. Except
if when a
message is received, Openser finds the first available
child and does 
this by trying child 1,2,3... Is this the case?
this scheduling is done by kernel and there is no guarantee of a uniform distribution in case of low traffic.
Last (related?) question: There is a thread that the first receiver child starts, what is its purpose?
you mean a process (there are no threads in openser). it might be a listener of mi_fifo. 

Regards,
Bogdan
