Hello !
I have a problem and it seems that some people have it also but no one has
an answer for it.
I've searched thru courierusers mailinglist and thru this mailing list but
i can't find a solution to this matter...
Here it goes..
I have a fedora core 5 os and vpopmail 5.4.13 with the cumulative patch
made by Bill Shupp, all works ok but the imap authentication service... it
seems like when the server is not used or it is used rarely (nightime) it
has the habit of refusing authentications of valid users because the mysql
server has gone away message !
The weird thing is, after i made some reading, it does not happen in the 8
hour interval wich is the timeout for mysql it happens randomly and when
it does i discovered that restarting the courier-authlib daemon
temporarely fixes the problem until next time...
So, i made an hourly cronjob that restarts the courier-authlib as a
quick&dirty fix until i find where's the real problem but it seems that
this does not work as well in the morning i still find that imap refuses
authentication...
Can some one help me with this, i'm not a complete noob but this is really
over my head and i would really appreciate some help or some indications
of what to read in order to understand what's going on.
This what the logs say for today, sorry for the large message
Max connections in mysql is set to 250 via my.cnf
