Re: Very high CPU Usage!!
BCheck the list archive. There was a thread on this a few weeks ago. The Bapparent cause was compiler shipped with RH7.0, I believe. -Bill Actually, I am not running RH7.0. I am running debian 2.2 r2(glibc21+egcs). Now I had to kill the processes manually. I have only seen this problem once. It has been four days since I killed the processes and the problem has not reoccured. I am not running tcpserver with the -p option (reverse dns) and the dns's in /etc/resolv.conf are ok (local djb dnscaches). The mysterious processes where a total of three, each consuming 33.3%. I am only running 10 domains on that box, and using cdb. Some hints, at the moment I ran top and saw these crazy processes, they were running under command "domainname" which was one of the 10 domains hosted on that box. This is also the only domain that has roaming users popping in. All other 9 domains' users access their mail through sqwebmail. One of my local dnscache's was down a while before I noticed this because of a power surge, if that could be related (maybe the user popped in at the moment the dns was down). But again, I do not have the -p option to tcpserver in my rc.pop init script. I just hope to unveil this mysterious behavior before it burns me a cpu. TH
RE: Very high CPU Usage!!
How large are these users' mailboxes? I vaguely remember someone reporting high cpu usage and it was because the account they were checking had so many emails that it would slow down scanning the directory to find the number of messages. __ Chris Bolt [EMAIL PROTECTED] http://www.bolt.cx -Original Message- From: Tamer Hassan [mailto:[EMAIL PROTECTED]] Sent: February 21, 2001 7:31 AM To: [EMAIL PROTECTED] Subject: Re: Very high CPU Usage!!

Hi, I have been running vpopmail for a long while and it was very smooth. Now I recently upgraded to 4.9.8 (still using cdb) and i am hosting only 10 domains on that box. After a while, I was logging on to the box and noticed it is slow (P-III 650 Mhz., 128MB PC133 Ram) so i wondered why! I ran top and I saw three vpopmail processes running, each consuming CPU 33.2%-33.3%. That is 99.9% cpu usage! Email in both directions works ok with no slowdowns, but I just wonder WHY vpopmail is consuming resources this high? --Tamer
