 SMTP jobs QTSMTPCLTP and QTSMTPSRVP consuming high CPU
SMTP jobs QTSMTPCLTP and QTSMTPSRVP consuming high CPU
Hi,

I am on V5R4.There are 2 SMTP jobs QTSMTPCLTP & QTSMTPSRVP which are consuming lot of CPU and taking the CPU to 250 % .This causes the users to comaplian of slow performance.

This is now a regular feature.

Can anybody suggest a solution for this so that the CPU can be brought down.

Many Thanks

Hughes Williams

Hi TomLiotta,

When I click on the relay restrictions via i series navigator,I can see the following:

Allow Relay messages:All

Please advice if the configuration will need any change.

Thanks

Allow Relay messages:All

In short, anyone in the world who has found a route to your service is allowed to use it to relay their e-mail. You might soon start finding out that your domain has been widely black-listed.

You show two jobs involved — QTSMTPCLTP, the SMTP client, and QTSMTPSRVP, the SMTP server. If both jobs remain busy, then both sides are doing work.

If you have no specific relay configuration in mind, set it to *NONE. Without knowing more about your networking, I can’t say much more. Review the results and post back if specific issues need attention. Things can be smoothed out in steps. And note that you can always undo the setting if necessary.

You might consider ending and restarting SMTP; but there might be numerous legitimate e-mails queued, so take care in how it’s done. Take notice of any changes in system resource utilization by either job.
