Those are fairly large log files, how many incoming and outgoing messages are you processing a day? What is the configuration of your server and what do the utilization statistics look like during peek processing times? Are you running Declude for spam processing or virus scanning or both? Also, what version of IMail are you running and is it updated to the latest patch levels?
You say that upon stopping and starting the process things went back to normal. Was it the SMTP service that you cycled? If you do a "netstat -an" from the command prompt when the server is stalled like this, do you see that the server is still listening on port 25? For example: ===== C:\>netstat -an Active Connections Proto Local Address Foreign Address State TCP 0.0.0.0:25 0.0.0.0:0 LISTENING TCP 0.0.0.0:110 0.0.0.0:0 LISTENING TCP 0.0.0.0:143 0.0.0.0:0 LISTENING ===== And if it is still listening on port 25, do you see lots of established or stalled inbound and/or outbound SMTP connections: ===== TCP xxx.xxx.xxx.xxx:25 xxx.xxx.xxx.xxx:2595 ESTABLISHED (incoming connection) TCP xxx.xxx.xxx.xxx:25 xxx.xxx.xxx.xxx:3065 ESTABLISHED (incoming connection) TCP xxx.xxx.xxx.xxx:2706 xxx.xxx.xxx.xxx:25 ESTABLISHED (outgoing connection) TCP xxx.xxx.xxx.xxx:2784 xxx.xxx.xxx.xxx:25 ESTABLISHED (outgoing connection) ===== showing possible SMTP/SMTPD thread saturation, meaning no more listening (SMTPD) or delivery (SMTP) threads available? Sorry for all of the questions, but I'm just trying to get a better understanding of how you systems is setup and configured, and if it is a possible resource issue.
