SH WWW server in 33_05
PB We have switched to 33_05 two hours ago. Everything seemed to be ok with the www server on the beginning but after some time the number of servers started to decrease and the number of front servers started to increase. Now we are not able to run servers at all neither from the front nor as a separate server (on port 4001) using option 6 from www_monitor.

Bellow is a small part taken from later part of the log file:

...
Server No. 77 can not connect to any of the servers
Main front is checking all www_servers
Server not running on port 4010, Running new server
Server not running on port 4011, Running new server
Server not running on port 4012, Running new server
Server not running on port 4013, Running new server
Server not running on port 4014, Running new server
Server No. 81 Initialized from Address 195.113.78.6:10078
Server No. 78 can not connect to any of the servers
Server No. 79 can not connect to any of the servers
Server No. 80 can not connect to any of the servers
