Dear All,
Recently, I chose to install and run Squid 3.2.1 on Debain Weezy/SID
(64 bit) with 4 workers
At the beginning every thing went well, but when the system goes under
loads of 20 users (more or less) I lose workers sequentially until
there went no kids to process the requests.
Which appears to be the real problem. Question is how is it happening?
what else is happening when the kids disappear?
In this time I have to
restart the squid to solve the problem temporarily.
The cache log shows following error (part of the log):

Um, you said "Restart" ? not "reconfigure". The above is the result of
"squid -k reconfigure"

FATAL: Unable to open HTTP Socket
Something else is still using the particular port.... probably kid4 above.
Sadly we do not print out the process which is reporting FATAL for a
better trace. That is another bug which needs to be fixed.
