We have that problem running on a Dell 2300 (PII450 w/512 Meg RAM) as well. We
are using Linux kernel 2.2.18pre11 and it hasn't happenned as much lately. What
OS are you using?

The table doesn't get cleared when mysqld restarts. However I have noticed that
when a user logs out their session record does not get deleted from the active
sessions table. Is this normal behaviour?

Subject: problems with sending an email

Hi
I have some problems with sending an email. When I put button send IMP shows
me:
Warning: errflg=2, text=Can't get status of mailbox {localhost:110}: invalid
remote specification in /usr/share/horde/imp/status.php3 on line 112

in IE ... and 
Document contains no data.
 in Netscape.
Have You got the same problem ???

I use Debian (potato) imp 2.2.3 php3 3.0.17 and mysql 3.22.32-3.
