Hi,
I am facing a wierd issue on dovecot while migrating OS of the server.
I have CentOS 5.2 32bit OS , Dovecot 1.1.20 with NFS on the server. When I am migrating it to CenOS 5.6 32bit with same Dovecot version. I compiled the same version i.e. 1.1.20 again. Now when I check the number of connection on this new server I can see only 8-10 connections for IMAP and 8-10 for POP3, where on old server I can still see the number of connections crosses 500+. I checked system level configuration which I found identical, limits set to same as old server, still no change in number of connections.
I even tried the above exercise on CentOS 5.6 64bit version. again the result is same. I have tried all the changes/configurations I could think of. Can you please help me to sort out this issue?
dovecot -n output ;
