Constant Timeouts on IMS5.2p1
Constant Timeouts on IMS5.2p1
We currently have a major issue with IMS5.2p1 running with IDS5.1. Users who make IMAP connections keep getting asked for their username and password every so often. Also a lot of them get a message saying their IMAP connection has timed out. This happens with pretty much all clients including MS Outlook, Outlook Express, Netscape Messenger and Evolution. Has anyone else seen this problem before, and can someone please help me eradicate it.
Thanks

You cant really access it via command line editor. Since the directory now stores its config info in ldap you would either need to use the java console to change it, or go into the ldap directory and under cn=config make sure that nsslapd-idletimeout is set to 0
You can do this with ldapsearch or using an ldap browser
Three things to ckeck:
1. Do you have a firewall between your server and clients? If so, it may be set to close idle connections too agressively.
2. Is the IMAP idle timeout set to something other than 30 minutes on your server? It should be left at 30.
3. You wouldn't by chance be using Resonate for load balancing?
I have experienced the exact same issue. The problem was in the firewall. Since the mail server is in the DMZ and the clients are on the LAN side, all traffic passes through the firewall.
I discovered that the firewall had a timeout of 5 minutes! This of course overrode any setting in iMS with regard to timeouts. Changing the firewall's value to something more realistic solved the problem.
