Squid default file descriptors number changed?

[Alexey Suslikov]

Hello [EMAIL PROTECTED]

Looks like default file descriptors number changed with Squid 2.7.

2.6 allocates 1024:

2.7 allocates 128:

2008/08/02 08:58:32| Store logging disabled

and cache.log fills with

2008/08/03 13:30:02| WARNING! Your cache is running out of filedescriptors

"max_filedescriptors 1024" in /etc/squid/squid.conf remedies the problem but
this new default in 2.7 is really strange.

Additionally, changelog for 2.7 contains:

Changes to squid-2.7.STABLE1 (27 May 2008)
...
        - max_filedescriptor squid.conf option
        - Clean up filedescriptor limitations, and handle comm loop
          restrictions proper
...

So maybe number of filedescriptors was hardcoded in 2.6 to 1024 but it is
not true for 2.7 any more?

Thanks.
