To all,

We are running.
We have Dual Pentium III Xeon 500.
Using IMail 6.03, 6.04 has too many bugs...
We have about 300 users that use ONLY! web-mail from 08:00am -> 17:00pm constantly.
About 110 of those 300 are using Imail without SSL and rest 200 users are forced to
use SSL all the time.
CPU usage is 30->100% peaks all the time. Jumping around...
We have huge problems with hanging. SSL seems to hang totally randomly. Once per day,
sometimes 5-6times per day and for awhile IMail runs smoothly for a week or so without
rebooting.
When SSL side is hanged up, inner port (8383, local intranet) works fine, few times
has occured that both sides are hanged up (non-secure/secure)
Only resolution for this problem is restart web-messaging service. But this action put
us in difficult situation, 'cause when stopping service, those 110 users that uses
inner non-secure port will be dropped out from webmail and they have to login again.
Messages are lost etc...
We have concluded that SSL is the only problem here, 'cause when it hangs, non-secure
port works and restart service help. We will discontinue using SSL in early 2001,
because we are building Intranet and extranet that is based on smart-id security cards
and then SSL will no longer be required.
Not very nice situation, but we have learned to live with it.
IPSwitch has been unable to help... and KB also.
>>If its only hardware, not a problem,
But when it comes to software... you'r screwed...
