Hello all, I have a trouble with my two mail servers where the users's maildir are. I use Courier Authdaemon with PAM_LDAP authenticating against a M$ Active Directory to serve imap, pop3 and maildrop. More than 8.000 accounts. The MTA is Postfix looking up for users in M$ AD directly.
Each 30 days I have to reboot both servers because the memory is all used. There's no cache memory, buffers or something else. I already tried echo 3 > .../drop_caches But with top or htop there's no process consuming more than 0,1% of memory (I have 8GB of RAM). If I stop all process, the memory stills is full, and I already tried to leave all process stopped more than 1 hour and the memory keeps all used. I think it's a memory leak. My servers are Debian Etch with: ii courier-authdaemon 0.58-4 Courier authentication daemon ii courier-authlib 0.58-4 Courier authentication library ii courier-base 0.53.3-5 Courier Mail Server - Base system ii courier-imap 4.1.1.20060828-5 Courier Mail Server - IMAP server ii courier-imap-ssl 4.1.1.20060828-5 Courier Mail Server - IMAP over SSL ii courier-maildrop 0.53.3-5 Courier Mail Server - Mail delivery agent ii courier-pop 0.53.3-5 Courier Mail Server - POP3 server ii courier-pop-ssl 0.53.3-5 Courier Mail Server - POP3 over SSL ii courier-ssl 0.53.3-5 Courier Mail Server - SSL/TLS Support How could I confirm that memory is used by a process A or B? Could It be something with Courier? Some trouble with Courier + PAM + MS AD integration? Thanks for any help ( I still have 12 days before next needed boot :( ) Luiz ___________________________________________________________________________________ Para fazer uma ligação DDD pra perto ou pra longe, faz um 21.
