Actually, I found in the archives that I should increase login_process_size if I'm not running with login_process_per_connection. I have done this and that seems to have taken care of the malloc failure.

All of my customers who had IMAP SSL problems are reporting that the problem is fixed now that I have increased login_process_size to 64 MB. In just two hours though the imap-login process is up to 33 MB, and continuing to grow. Is that normal? This particular server handles 1200 IMAP connections and 800 IMAPS connections concurrently on average.

I don't know how much memory each SSL connection takes, but I'd suggest increasing the memory limit even higher, maybe even 256MB. If it continues to grow up to it then I guess there's a memory leak somewhere.

After watching it for the past ten days, the imap-login processes on our five Dovecot proxy servers are hovering at between 32MB and 36MB each. So it doesn't look like a memory leak here. The proxies are running great.

Thanks, Bill
