Hi everybody, I installed qmail (v. 1.03 running on Solaris 2.6 for x86 - JUST ! (without any patches)) with tcpwrapper ucspi-0.88 and multilog from daemontools package (v. 0.70) all them compiled with gcc 2.95.2 running in 4 machines PIII - 500Mhz with 256mb RAM. In my DNS I have smtp.ig.com.br pointing to IPs addresses of that four machines trying to make some kind of load balance (Probably soon I will replace this by IPVS or something like that (Altheon, etc). The total amount of messages that are sent through those machines are aprox. 1.5 million by day (!) . I have set remote and local concurrency to 255 (and I change the limit in conf-spawn to 255 and recompiled qmail after that). My tcpwrapper is configured to 400 simultaneous smtp connections (per machine). The remote and localconcurrency stay between 30-150 connections so, I think that 255 limit isn't problem by now (Maybe in future I will need to install the patch to concurrency above 400). Memory and wait I/O isn't the problem. The number of file descriptors are ok (2048) now (Now I don't receive messages tell me that was not possible to open a pipe (or something like that)). The problem is the fact that I'm having too much defunct process. Usually I have between 350-500 process running by machine. From that, normally I have between 90-120 defunct process per machine. Anybody have ANY idea about what can be causing this ? Is there any patch to correct this problem, in case of this be a well know problem for my plataform ? PS. multilog and tcpwrapper are in PATH and this problem NOT started after I reboot my machines ;-) Any help will be very appreciated ..... Thanks in advance...
