Hello all,

I really need help with a problem that been getting worse over the last couple of days. Nagios is reporting the following:

Service: IMAPs server
Additional Info: CRITICAL - Cannot make SSL connection

Service: Mailping
Additional Info:
UNKNOWN: Unable to connect to "server ip address" : connection failed IO::Socket::SSL: Timeout

CRITICAL - Socket timeout after 10 seconds

then after a couple of min

Notification Type: RECOVERY

Service: IMAPs server
Host: Main Server
Address: mail server ip
state: OK

TCP OK - 0.014 second response time on port 993 [* OK [ AUTH=PLAIN AUTH=LOGIN] mail.server.com IMAP4rev1 2003.338rh at tue,
OK: All email received


durring this time mail clients, outlook/thunderbird will lose/report lost connection to imap server - also, squirrlmail will give an error message on login

any clues on where and how to troubleshoot this error? what tool would tell me if the error have to do with server overload? tools to analyis the server imap?

Thanks for you time
mail server is is rhel4, sendmail, uw, spamassassin, clamav
