Problem with IMAP connection limits
Posted: Mon Jan 08, 2007 7:37 pm
I'm having an issue where our server is periodically not allow IMAP connections. The client says it cannot connect and I can't connect to SWA either. I believe it's due to IMAP connection limits
When I do:
omshowlog -l 5
I get a bunch of stuff but recently a ton of:
WARNING IMAP Server Da(IMAP Server Pr) 01.08.07 16:21:50
[OM.DMON 2107] Maximum number of IMAP connections exceeded
I did some research. There are settigns in general.cfg for this. Here are what mine are set at (which I believe are default values):
IMAP_CONNECTION_LIMIT=500
IMAP_CONNRATE_LIMIT=10
We only have 30 users. Is it possible that we are running up against these limits? Doesn't seem so but I think IMAP clients tend to open multiple connections to the server.
I found knowledge base info that says that setting those both to "0" will make it limitless. My server is ok on resources so I'm wondering if I should go that route. Otherwise if there are other suggestions as to what might be causing this I'm listening.
Thanks,
MG
