Re: [squid-users] Re: squid crashes many times in a day

Hi Amos,

Since last week, I am facing below issues and really want to resolve
it.While moving around and looking on Google, I found that some similar
post for below problem in 3.2. series also. Can you please comment on
below problem that is it open bug with 3.1 and 3.2 series ? Or is it
resolved in current 3.2 series?

Your inputs are highly appreciated.
