Re: MaxConnect
Thank you and to all who responded. Currently CPU is very good.
I am concerned that there are mutex waits ('S' as the 1st flag 2nd
column in onstat -u) When that happens it sometimes freezes
the whole system. It seems that it only occurs when a lot of users
log off at once and I was therefore wondering if MaxConnect would
help.
