I am running qmail and vpopmail. Hi. My qmail server has been humming along quite nicely. Its a small server with a small amount of users. I noticed logging in via POP had become very slow so I decided to talk a closer look. I notice that the tcprules process and the vchkpw process is sometimes using up to 90% of CPU consitently. I also noticed a lot of large files in the /etc/tcprules.d directory with the following type of names: qmail-smtpd.tmp.24168 qmail-smtpd.tmp.24105 etc I tried restarting the pop server and qmail but it seems to just continue on taking up so much CPU, same with rebooting. I only have 100 users on this server so I dont think I should have any problems. How do I go about debugging this ? It has been working fine for about 5 months until this. thanks ! Tony
