Subject: [IMail Forum] SMTP hogging cpu,
possible SMTP attacker
Over the last few days I have been experiencing
some very heavy load on our Imail server from SMTP. I am running most recent
version of Imail server. I looked in the sys logs today and saw a bunch
of weird entries that i have never seen before, these entries just keep
showing up throughout the log and seem to be present around the same time as
SMTP is using alot of cpu time. The log entries look like this:
12:05 15:50 ODBC(155044339) (Table: (null))
Initialize:SQLDriverConnect (Check userid and password on
server.)
12:05 16:26 ODBC(162605339) (Table:
tblUser) IsValidTable : (Error: # HY000 : [Microsoft][ODBC SQL Server
Driver]Connection is busy with results for another hstmt)
12:05 16:26
ODBC(162605339) (Table: tblUser) CreateTable : (Error: # HY000 :
[Microsoft][ODBC SQL Server Driver]Connection is busy with results for another
hstmt)
These lines do not make any sense to me. It looks
as if someone or something is trying to create table's within my user database
or something like that. Could this be someone attacking our
server?
