Actually I'm not using the eligible list (QUICKDSP ON for this machine) and I've a lot of CPU (10 z990 IFLS) and memory 22GB plus 14GB of expanded. The sendmail virtual machine has 2 virtual processors. I was thinking to increase to 4 to avoid some processor contention but I do not know so much about it.
I know that 1.5 GB memory is too much. It will take a while to split the workload in two different machines. I have 4000 email users that have to change their configurations. They point to the same server (same hostname). It is not common to see this type of configuration, both services on the same machine... The best thing to do now is to reduce the machine virtual memory (I have the free -m statistics) and upgrade the sendmail. I'll do those things first and see what happen. This problem occurs almost every day at same time at 8AM, when they have the peak...

You're probably getting forced into the eligible list and your virtual machine is so large that it's never getting scheduled again. Break the two functions (mail delivery and POP access) into two different virtual machines, reduce the size of the virtual machines to 128M, and use VDISK to provide large swap disks. This will drastically improve performance. > sendmail version > 8.11.6. You *really* should upgrade your sendmail. This version has numerous problems. Consider switching to exim as well -- if you're doing any real volume, it's much more efficient than sendmail. -- db ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 Esta mensagem foi verificada pelo E-mail Protegido Terra.
