[squid-users] Squid 4.3 assertion failed

Hi all,

Environment:

The error (bug?):

   assertion failed: http.cc:1530:
"!Comm::MonitorsRead(serverConnection->fd)"

Sometimes cache.log show this and squid goes down, and sometimes just it
appears in the log and squid does not stop.

I don't exactly remember when this start to happen but, I think that since
squid version >= 4.2 or 4.3

Any idea?

Thank You
