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
Thank you
George

Hi George,
I made a fix related to subst_user() - could you apply it
and give it a try?
Thanks and regards,
Bogdan
