Hello,

I do agree that it may be harmless, however I didn't get this message at
all with kernel 2.2.16 (if I revert back to 2.2.16 it stops). I have
only seen this since upgrading to 2.2.18 (as did the person who wrote a
similar email in the list a few months back).

In addition, I belive this error only occurs once I go past the 1024
filedescriptor point; here is what I have done to increase the FD limit
under 2.2.18:

ulimit -HSn 4096 -n 4096 (in rc.local as well as my RunCache script)
echo 4096 >/proc/sys/fs/file-max (in rc.local)
edited /usr/include/bits/types.h to change __FD_SETSIZE to 4096
compiled squid.

Interestingly enough, with 2.2.16 I don't have to edit
/usr/include/bits/types.h, I leave the default 1024 value and it will
still see 4096 file descriptors with 2.3STABLE4 (2.4PREXXX does only
compile with 1024 though). However, if I do not edit types.h before
compiling or using squid on 2.2.18, it will only allow me to use 1024
FDs no matter what I cat to /proc/sys/fs/file-max.

Is there a link?

Thanks again,

Chris
