Re: [SOGo] Parent process consumes 100% cpu

I need to correct myself. The backtraces are only identical up to line 16. It seems that this is not code from SOGo. So it may be a bug in gnustep or libc. Since this server is still running debian lenny, it may be fixed in squeeze. Upgrade is planned anyway. I'll write again if the problem stil

Hi, I tried different numbers of sogod workers. Nothing worked. Since this happens in our production server i can't investigate the problem if it happens through the day. Fortunately is right now happening an everyone already left the office. This means 2 things: 1. There is not really any lo

Thanks for the fast answer. How many workers would you suggest? I tried it once with 6 and 10 but because of the memory consumption (swapping) the server became even less responsive. Right now we are using 4 workers. Couldn't it be that this aggressive waiting strategy could even prevent the

Hi, In the last weeks we are facing a problem with our SOGo server. From time to time (sometimes twice a day) the parent process consumes full cpu. We tried several things and are out of ideas right now. It looks like the child processes are somehow occupied in a request but do not need any cp
