We have done several tests with differents QUERY_STRINGS lengths.
With 4065 characters or less, the CGI runs fine but with 4066 no.

I think the environment size of our machine is 4KB.

Our OS is Solaris 2.5.1
Is the environment size equal to max bytes on queue(MSGMNB)?
Is this value tunable?

The value of MSGMNB is the maximum lenght of a messages queue
in SYSV IPC.
The maximum size of the environment, or better, the length of
all arguments to the process plus the environment is fixed at
ARG_MAX bytes. Under Solaris, this is 1MB and you can easily
check that Solaris accept larger environments than the 4k with
something like
YOOHOO=`cat /var/adm/messages`; export YOOHOO; sh -c 'echo $YOOHOO|wc'

I suppose the web server you use limits the size of the QUERY_STRING somehow. If this is the case and you've got the
source code, you might be able to change this.
